Azrael: S Tier: This guy is just about a must-take, and not too expensive for how much he brings. CP is a precious thing in 10th, and he gives more just for being there. Sustained Hits 1 is a great buff for a shooting or melee unit, particularly one with decent volume of attacks, and the 4++ he gives his unit is the cherry on top. Stick him with some Hellblasters and go melt stuff, he's awesome!

Belial: A Tier: Belial has become something of a character assassin, giving his unit Precision on critical hits in melee. Given that he can only lead Terminators, I might suggest sticking him with a Deathwing Command Squad or perhaps some Deathwing Knights (although those are probably a bit too expensive). If you were already planning on bringing a few Deathwing of some kind, he's a good add.

Sammael: B Tier: Sammy's good, and giving an already-fast unit like Black Knights or Outriders Advance & Charge is great, but I'm not entirely sure it's worth his price tag. Then again, mobility is usually king in 40k, so maybe it's worth it.

Ezekiel: B Tier: Ezekiel gives a solid buff to a unit, but his main downside is that there's nothing amazing that he can actually lead. Vanguard Veterans are probably the best choice, and Ezekiel isn't too expensive as an add-on to that unit, so maybe the play is 5 of those plus him in a Razorback.

Asmodai: C Tier: They keep doing my boy dirty. He's certainly cheap enough to maybe be good, but again there isn't anything amazing for him to lead. He could potentially be a decent candidate for a Command Squad as they would benefit well from his rerolls (seeing as how a couple of them can take real melee weapons) but that unit is just too expensive for what it does. Ezekiel is just a better choice most of the time.

Lazarus: B Tier: Fight on death is a strong ability, and it's seen across a number of different armies in the new edition. For that reason, Lazarus probably wants to go with a dedicated melee unit, and that means either Bladeguard or Assault Intercessors (hint: pick the Bladeguard). As he has the Captain keyword, he can even pair with certain other characters to make a strong unit.

Lion El'Jonson: S Tier: He's a Primarch who is stupidly hard to kill and gives out some serious debuffs to the enemy, forcing them to either play at a disadvantage or find a way to neutralize him. He absolutely pays for this utility, but most of the time you'll happily find a way to fit him into your list. It certainly doesn't hurt that he also hits like a truck, either!

Ravenwing Talonmaster: A Tier: Not as nasty as in the previous edition, as he now has half the firepower he had before because Twin-linked. Still a decent tool to have, as he lets nearby Bikes and Speeders ignore cover, useful in a world where weapons generally have less AP than before. Probably don't take more than one anymore though. Actually funnily enough there might be a strange rules loophole that makes running more than one a good play: as a Fly Vehicle, a Talonmaster provides Lone Operative to another Talonmaster, so two or three of these next to each other grant each other immunity to shooting. I expect this to get corrected if it hasn't already been, but for now enjoy the jank!

Deathwing Strikemaster: A Tier: He's a Lieutenant in Terminator Armor, something regular Marines just don't get. He gives the standard Lieutenant unit buff of Lethal Hits to his unit, and on a big brick of Terminators that could actually be scary and make them more dangerous to enemy monsters and vehicles.

Primaris Captain: B Tier: As a unit leader, he's generically “fine”. The ability to pop a stratagem for free and even if it's already been used in the current phase is nice. The issue is that units he can lead have better, more exciting options for leaders.

Captain in Gravis Armor: C Tier: He has the standard captain ability (free strat once per round) but his other ability only benefits him personally and helps him stay alive if his unit gets dirtnapped. He can only join walking Gravis units, and none of those really need him. Could be interesting paired with an Apothecary Biologis leading a brick of Aggressors, but that's a fairly expensive package.

Captain in Phobos Armor: B Tier: He has a redeploy ability, but only for Phobos units. Crucially, it's timed such that you'll know who has the first turn before you pop it, so it can be used offensively or defensively. A neat thing to remember is that Invictor Warsuits have the Phobos keyword, so this could be good if Invictors end up being good.

Captain in Terminator Armor: A Tier: Gives charge rerolls to a Terminator unit he leads, and in Dark Angels the unique Deathwing units can indeed be led by this guy. This combined with the standard Captain free strat ability is great, and I expect to see these lead Deathwing as a nice alternative to Belial.

Captain: C Tier: Same as Primaris Captain, but only leads Firstborn units (Tacticals, Assault, VanVet and Command Squads), and has more weapon options. The relatively lackluster nature of those units means this guy isn't as useful as he could be.

Captain with Jump Pack: B Tier: If Jump Pack Assault Squads or VanVets turn out to be good, this guy will be good, as his ability is pretty good with them. Those units and this character pay a bit of a premium for their jump packs though.

Captain on Bike: B Tier: His buff makes it so a bike unit can advance and still shoot all their guns, which is nice, but they can't charge afterwards, meaning this guy is like a slightly worse Sammael. He is significantly cheaper, though, so might still have some play, particularly in bike-heavy strategies.

Primaris Lieutenant: A Tier: Another very solid buff character, and can pair with a Captain or Chapter Master. Lethal Hits is just a nice ability to add to just about any unit, and lets said unit punch above its weight. Works well with Azrael or Lazarus to further enhance the units they lead.

Lieutenant in Reiver Armor: D Tier: Reivers, even after three editions, still just aren't that good, so adding this guy to them is just throwing good points after bad. Lethal Hits, as mentioned above, is a nice buff, but they just don't have any weapons that are worth buffing.

Lieutenant in Phobos Armor: C Tier: Has a bit more flexibility in which Phobos unit he can join, but still doesn't really add anything useful to them (Lethal Hits matters a lot less on the weak weapons carried by Incursors/Infiltrators/Reivers). The shoot and scoot ability is cute and might allow some trick plays.

Lieutenant: C Tier: Oddly the most expensive vanilla Marine Lieutenant. In addition to the standard Lethal Hits, he give the ability for his unit to fall back and still shoot or charge. This could be nice on VanVets or Assault Marines, but Tacticals can already do this and Command Squads are probably too expensive.

Lieutenant with Combi-weapon: D Tier: His weapon is good vs. Tyranids, which is funny but way too specific, and his other abilities just don't add enough for his points.

Primaris Librarian: A Tier: Gives his unit a 4+ Invulnerable Save, which is a great thing to have on a lot of different units. And he can even join a Desolation Squad, which is great.

Librarian in Phobos Armor: B Tier: Grants Stealth and protection from shooting by any enemy outside 12”, which is nice, but he can only give this to Phobos units. Probably best used with Eliminators.

Librarian in Terminator Armor: A Tier: Another great character option for Terminator units. Sustained Hits is a great buff for regular shooty Termies, as they carry Storm Bolters and can take Assault Cannons with lots of shots, so plenty of chances to proc those extra hits. It does work in melee too, of course.

Librarian: C Tier: Same as Primaris Librarian, but can't really join anything you want to give extra durability to. VanVets can take Storm Shields for the same save, and it probably isn't worth spending the points to give it to the other Firstborn units.

Librarian with Jump Pack: B Tier: If you want to run a jump pack melee unit (Assault or VanVet squad), this is possibly the best choice to lead it. Extra AP adds good value to a unit with that kind of attack volume.

Primaris Chaplain: B Tier: Bonuses to wound rolls are pretty strong, this guy is probably a good add for Bladeguard. Assault Intercessors would like this buff too, but I'm not sure it's worth it on them. Fixing a unit that gets Battle-shocked can be good, but some of the Dark Angels detachment's enhancements and stratagems get better when a unit is Battle-shocked, so it's potentially counter-synergistic.

Chaplain in Terminator Armor: A Tier: Has the standard wound buff of all Chaplains, but this model lets you apply mortal wound protection to Termies. Mortal wounds are a weakness for tough expensive models like Termies, so this could be good value to keep them alive. Possibly best on Deathwing Knights, who will REALLY appreciate the mortal wound protection and the +1 to wound.

Chaplain on Bike: S Tier: If you're running bikes, you probably want this model. Devastating Wounds is powerful on all their shooting (even if it's just bolters, you get enough shots to reliably fish for 6's). If you can get a cheeky 6 on a melta shot, that's even better! Only downside is you do have to get pretty close.

Chaplain: C Tier: Same abilities as the Primaris version, but can't attach to anything you need to put these buffs on. Walking VanVets maybe, but there are other buff characters for those.

Chaplain with Jump Pack: C Tier: Putting out mortals is nice, but it's unreliable. +1 to wound is nice to have on VanVets, so this guy might be better if those turn out to be good.

Primaris Techmarine: B Tier: If you run a lot of vehicles, you probably want this model around. Goes full murderhobo if a vehicle dies, which is funny, but you don't bring this guy for his combat. Just keep him near the back and fix vehicles when they get busted.

Techmarine: C Tier: Strangely costs more than the Primaris version, but does have more wargear options. Which you probably won't take, because only the Axe gets better if a vehicle dies. At least do take the servo-harness though; it's literally free extra guns so go nuts.

Astartes Servitors: C Tier: You probably won't bother with these, but attached to a Techmarine they can provide some cheeky firepower. I list these with characters because they are not worth considering without a Techmarine (and probably still not even with one).

Primaris Company Champion: B Tier: Yet another good leader choice for Bladeguard; probably not worth it with anything else (maybe Assault Intercessors?). Can potentially assassinate enemy characters in melee thanks to Precision on his weapon.

Primaris Apothecary: A Tier: Resurrecting models can be really strong; probably best on units like Hellblasters or Desolation Squads. Can combo well with Hellblasters to bring them back when their Hazardous tests blow them up.

Apothecary Biologis: C Tier: Probably only truly useful on Aggressors, as they actually have meaningful melee to proc his extra OC. Lethal Hits is a good buff to have on those, as it lets them punch up into stronger enemies a bit, although they do already have Twin-linked on their fists and therefore don't need the buff as much (the guns don't mind it though).

Primaris Ancient: C Tier: Probably not worth the points, but more testing is needed as increasing OC could be very powerful, especially if it still works while the unit is Battle-shocked (except as Dark Angels, we already have OC1 when Battle-shocked).

Bladeguard Ancient: A Tier: If you are running Bladeguard, this guy should definitely be considered, as more attacks on those is always welcome. He can even combo with a Captain, Chapter Master, or Lieutenant, and might pair well with Lazarus.

Ancient in Terminator Armor: D Tier: He gives +1 to hit for units under starting strength, which doesn't always matter as most Terminator units have Fury of the First (or the equivalent ability baked into another ability). +1 to wound is nice though, and if you're not shooting/fighting the Oath of Moment target it matters more. I personally don't think he's worth the points; I'd rather just invest in a Deathwing Command Squad intead.

Judiciar: S Tier: Of all the characters that can join Bladeguard, this guy might be the best. Fights First is an incredibly powerful ability, making a unit with it difficult to come to grips with in melee, as to hit them you first have to survive being hit by them. Can also murk enemy characters with his own weapon, and gets more attacks each time he does so.

Intercessor Squad: B Tier: Possibly our best Battleline option, if for no other reason than “sticky objectives”. They won't win games by themselves and probably don't warrant an attached character, but they can hold take and hold ground.

Infernus Squad: B Tier: Auto-hitting weapons that force a Battle-shock test could be a good tool to have in our back pocket. They'll also clear hordes of gribblies reasonably efficiently.

Assault Intercessors: A Tier: The other candidate for best Battleline; unlike normal Intercessors these are better for taking objectives away from the enemy, whereas the ones with rifles are better for holding onto ones you already have. Always take a weapon upgrade on the sarge, and if you want a big unit you might consider some kind of buff character.

Heavy Intercessors: A Tier: No sticky objectives, but these are really hard to shift with small arms and their own guns aren't terrible for the price. Don't bother with a buff character.

Infiltrators: A Tier: Guns are underwhelming, but the ability to infiltrate and prevent Deep Strikes within 12” of them is a nice utility, especially against armies like Daemons. And they're cheaper than Intercessors!

Incursors: A Tier: Taken in small units these guys provide some good utility. The haywire mine is a way to do some cheeky mortal wounds, especially to tough vehicles. They don't infiltrate anymore, but they do get the Scout rule for a pregame move. A good way to buff the rest of your army's shooting against a key enemy unit.

Tactical Squad: C Tier: Cheaper per model than Intercessors and they get the option to take better weapons (which you definitely should), but you are stuck with 10 dudes. Being able to fall back, shoot, and charge is very nice, but you aren't going to charge with tacticals, like, ever.

Scout Squad: B Tier: You don't bring these for the firepower; you bring them for the utility they bring. Personally I'd skip these in favor of the snipers, but taking a unit of 5 in a Storm could be fun.

Scout Sniper Squad: A Tier: One of the better character hunter units in the game, probably better point for point than even Eliminators.

Bladeguard Veteran Squad: S Tier: Probably one of the best melee units in the game for their cost, and they have all kinds of good options for leaders.

Command Squad: D Tier: This unit is straight cabbage. They cost almost as much per model as Bladeguard, but just aren't as killy despite two of them having access to the good melee weapon options from the Astartes arsenal. The Apothecary resurrecting one every turn is cool until you realise the enemy can just easily wipe the unit before he gets a chance.

Vanguard Veteran Squad: B Tier: These models are fine. Not great, just fine. They do make a good retinue for Ezekiel, who makes them capable of turning hordes into fine pink mist. Anything beefier than that (like Terminators or Custodes) and they'll bounce hard.

Vanguard Veteran Squad with Jump Packs: C Tier: Less choices for attached characters, but definitely more mobile than their footslogging brethren. Not sure these are worth it over Assault Squads, honestly. Their weapons are a little better, but they cost a bit more, and they lack the Hammer of Wrath ability.

Sternguard Veteran Squad: A Tier: These guys are nice to have when facing enemy infantry, especially if they can get rerolls to wound. Not honestly sure whether the bolt rifles or combi weapons are better; both have Devastating Wounds, but the combis have Anti-Infantry 4+ and thus will proc them more. The bolt rifles have more shots (in half range), though, and thus are more generally useful (e.g. against non-infantry targets).

Reiver Squad: C Tier: This unit is clearly intended to gank characters in squads, but their weapons aren't that scary to most characters in the game. Forcing an enemy unit they charge to take a Battle-shock test (at -1 leadership) is potentially useful, so I won't write these off completely.

Aggressor Squad: B Tier: These guys are tough and with twin-linked on their fists can punch above their weight class, but you do pay for that utility. I don't think these are bad, but I'm not sure they're as good as terminators either.

Terminator Assault Squad: A Tier: Dark Angels love their Terminators, and the Teleport Homer can be a nice piece of tech to let this unit appear in some strange spots during your opponent's turn. I'd stick with the hammers and shields; the extra wound will come in handy when facing D3 weapons.

Terminator Squad: A Tier: Terminators are great, and the shooty variant are great all-around models who are tough and can shoot decently hard. Fury of the First gives great utility to avoid pesky hit/wound modifiers.

Relic Terminator Squad: B Tier: Not terrible, but the options on the regular ones or especially the Deathwing ones are better. At least they are slightly cheaper.

Deathwing Command Squad: S Tier: These guys, quite simply, rule. Take the full brick of 10 for best results; that Apothecary bringing dudes back is more viable in a unit like this, as unlike the power-armored squad this unit is very non-trivial to wipe out. Put a character in for maximum usefulness.

Deathwing Terminator Squad: A Tier: Sort of a hybrid of the regular and Assault Terminator units, and can mix and match their wargear. Kind of a fun way to get Fury of the First on Assault Terminators, as the Deathwing rule is literally the same.

Deathwing Knights: A Tier: Very expensive at 47 points per model, but the damage reduction and large number of wounds makes them very annoying to shift, and they have enough attacks at 3 damage that they'll pretty much murder anything you point them at. Definitely give them some kind of buff character if possible.

Centurion Assault Squad: C Tier: Expensive, and not as effective as they should be at killing monsters and vehicles (too few attacks, even with Sustained Hits 2). I'd personally rather just have Terminators with Chainfists.

Centurion Devastator Squad: C Tier: Like the Assault Centurions above, they are tough but just don't get enough firepower to reliably shift a vehicle despite seeming being optimized for that. Too expensive for what you get.

Assault Squad: B Tier: Footslogging Assault Marines are actually interesting. What a world we live in! Given their unit ability, I think keeping all chainswords is the way to go, with perhaps a good weapon on the sergeant and maybe a couple of Eviscerators. Take as many plasma pistols as you are allowed though, and give that sarge a shield!

Assault Squad with Jump Packs: B Tier: I love their Hammer of Wrath rule in general. Take those Eviscerators! Given the relative cost of the units, I think these might actually be better than jump pack VanVets.

Outrider Squad: B Tier: More expensive than regular Bikers, but more durable and better in melee (and better boltguns but nothing to write home about). Can bring along an Invader ATV in the unit for some real ranged firepower if desired.

Invader ATV: C Tier: Expensive, but it can bring decent firepower. It can also shoot back if someone shoots at a friendly mounted unit, but one ATV isn't really that powerful (and you can't take units of more than 1).

Bike Squad: A Tier: These guys are less durable than Outriders, but they are significantly cheaper and can take real ranged weapons (like plasma and melta). Can also bring along an Attack Bike, which is probably a good idea.

Scout Bike Squad: B Tier: Squishier than normal Bikes with only a 4+ save, but since every guy can take an Astartes Grenade Launcher, you should do that. They cost nearly the same as regular bikes and can't take other special weapons, so probably not quite as good.

Attack Bikes: A Tier: Has the same ability to reactive fire as Invader ATVs, but since you can bring 3 Attack Bikes the ability is much stronger on them. They are cheaper too.

Ravenwing Command Squad: B Tier: Probably too expensive for what you get, but not horribly so. Might be a decent retinue for a character like Sammael. Always bring the full 6 models; you'll need the extra bullet catchers.

Ravenwing Black Knights: S Tier: These guys get Anti-Monster and Anti-Vehicle when they charge, 'nuff said. Their weapons look weak with only 1 damage, but if you have a way to give them rerolls or other buffs they can still punch above their weight, and their shooting isn't too bad either.

Suppressor Squad: C Tier: These are a disruption unit more than a damage-dealing unit, but they aren't durable enough for the cost, and their effect isn't all that strong.

Inceptors: B Tier: These guys have the ability to get close to the enemy on their deep strikes, at the cost of being able to charge. Which is fine, because these guys would rather be shooting than fighting anyways. They can mess with your opponent's screening plans though.

Hellblaster Squad: S Tier: The Azrael Hellblaster Brick is back, baby! Seriously, put Azrael with a big unit of these bastards; he'll make them extra nasty. Maybe add a Primaris Apothecary to resurrect them when they die, too.

Eliminator Squad: B Tier: Sitting still and getting Devastating Wounds is pretty spicy on either of their weapons. I think the Las Fusils are probably better, as Dev Wounds lets them threaten even higher toughness targets, and you have Sniper Scouts for dealing with pesky characters.

Eradicator Squad: A Tier: These are a very good tool for dealing with higher Toughness targets, as they get full rerolls of hits, wounds, and damage against monsters and vehicles. They do have to get danger close to get full effect from their weapons though, so if they whiff they are most likely dead.

Devastator Squad: B Tier: These guys can be equipped with a variety of weapons to fulfill various roles, but are probably best used for anti-tank with Lascannons or Grav-cannons. They can ignore cover if they sit still, which is something they want to do anyway since they have Heavy weapons.

Desolation Squad: S Tier: Some of the best indirect shooting in the entire game. You definitely want some of these.

Invictor Tactical Warsuit: B Tier: Good value if you run a lot of Phobos units, but as Dark Angels we'd probably prefer more bikes and Terminators. Being able to get extra shooting when our Phobos buddies get shot is decent value, and the redeploy from the Phobos Captain is very nice on these.

Dreadnought: D Tier: The classic box dread is, unfortunately, trash at its price point. Almost any vehicle will do the same job better.

Contemptor Dreadnought: C Tier: Same problems as the box dread, but at least this thing gets 2 lives 5 out of 6 games. At its cost, it's gonna be frustrating when it fails to get back up though.

Ironclad Dreadnought: C Tier: Oddly it's cheaper than the box dread, but it's better in almost every way. Still not very good, mind you, but not terrible.

Redemptor Dreadnought: B Tier: Probably overcosted, but it's decently tough with its damage reduction. Best used as a mid-table bully that can shoot decently hard with the plasma and then charge if something gets close.

Brutalis Dreadnought: B Tier: Also overcosted, but hits like a freight train. At its cost, always take the multimeltas over the heavy bolters, and probably always take the talons.

Ballistus Dreadnought: A Tier: Priced to move, and has some of the best long-range firepower in our arsenal. Definitely worth a look as a source of anti-tank.

Storm Speeder Hailstrike: B Tier: With the AP of a lot of weapons reduced across the board, the ability to give other Astartes units increased AP against a hard target has significant value. The vehicle's own firepower is somewhat mediocre, however, except against squishy targets.

Storm Speeder Thunderstrike: A Tier: This vehicle has decent firepower vs. lighter vehicles, and its ability lets other units get +1 to wound something it shoots. This could be very key for taking down big targets like Knights.

Storm Speeder Hammerstrike: B Tier: This vehicle is an absolute menace to light vehicles. Its ability removes cover from an enemy unit hit by its weapons, which is slightly underwhelming compared to the other Storm Speeder types.

Land Speeder: C Tier: Expensive for what you get; it does make other units in your army with Blast weapons hit better and ignore cover against a single target (great for Whirlwinds or Desolation Squads). If you run a fair amount of indirect stuff, grab one or two of these.

Land Speeder Tornado: A Tier: Expensive, but its strafe ability is great for pumping out a few cheeky mortal wounds to a tougher squad. Grab an Assault Cannon and Multimelta for some decent firepower too.

Land Speeder Typhoon: A Tier: The “shoot and scoot” ability it has is one of the most annoying rules in the entire game; just ask anyone who has faced Aeldari or Tau in the past. Abuse it!

Ravenwing Darkshroud: A Tier: This unit will help keep some of your expensive stuff alive; very useful for bikes, particularly the more expensive ones like a Ravenwing Command Squad.

Ravenwing Land Speeder Vengeance: A Tier: Has the “shoot back” thing that Attack Bikes/Invader ATVs have, and it's actually scary from this vehicle. It still might be overcosted, but at the very least it'll draw fire away from your bikes because your opponent won't want to give you a free strong shooting attack.

Thunderfire Cannon: A Tier: At first glance these look way too expensive for the shooting they put out, but the Tremor Shells ability is worth every point.

Firestrike Servo-turrets: B Tier: Their guns are good, and firing Overwatch on 4's is pretty decent. Not sure they are worth the points, but probably worth a try in some lists.

Hunter: C Tier: They only get one shot, but against airborne targets it's almost always going to dump a pile of mortal wounds on them. Can be a great tool to soften up tougher flying targets like certain aircraft.

Stalker: C Tier: Like the Hunter, it's best against flying enemies, but it has enough volume of fire to be sort of okay against other stuff. Can really get spicy with Overwatch too.

Whirlwind: B Tier: Our other source of indirect firepower. Not as good as Desolation Marines, but can cause Battle-shock, which could be nasty if applied to an enemy unit on a home objective.

Predator Destructor: B Tier: This thing can do mean things to enemy infantry, as it has decent volume of 2 and 3 damage attacks, that get better AP when targeting Infantry.

Predator Annihilator: C Tier: This is the anti-big stuff Predator, and its ability is much less helpful than the Destructor's.

Gladiator Lancer: A Tier: This is what the Predator Annihilator wants to be. It actually has a good chance of just deleting an enemy tank in one shooting attack.

Gladiator Reaper: A Tier: This is one of the best anti-infantry platforms we have access to. The combination of Twin-linked, Sustained Hits 2 (when targeting Infantry), and Devastating Wounds on its main gun is just nasty.

Gladiator Valiant: B Tier: Decent at picking off lighter vehicles and monsters, generally I'd rather have a Lancer for that as it's cheaper. This vehicle has the potential to spike higher damage than the Lancer though.

Vindicator: B Tier: This tank is good and its ability to fire into a unit in melee with it despite its gun having Blast is pretty cool, but it is overcosted. Its damage is pretty swingy into big targets too, but generally decent.

Land Raider: A Tier: The Assault Ramp ability is absolutely money in the bank for units like Terminators or Aggressors, giving them a massive threat range. It certainly doesn't hurt that it also packs decent anti-tank punch with 4 Lascannon shots.

Land Raider Crusader: B Tier: 16 transport slots is kind of an awkward number to fill, although 6 Aggressors with a Captain and Apothecary Biologis can do it. The guns will shred lightly-armored infantry targets, but will struggle hard against anything bigger or with a decent save.

Land Raider Redeemer: A Tier: Not only does this thing have decent transport capacity, but it can be an absolute menace with its strong auto-hitting flame weapons on Overwatch.

Repulsor: A Tier: For its cost, this thing is absolutely GODLIKE! It's not as sturdy as a Land Raider as it lacks the 2+ save, but it has decent weapons overall, and the ability for a unit being charged to just jump inside can be useful.

Repulsor Executioner: B Tier: Its main gun is legit powerful, but I'm not sure it's worth the points, and it can't tranport that many models. Its ability makes it good for finishing off models like Knights that are already hurt.

Rhino: B Tier: The classic metal bawks is okay enough for its cost; what holds it back is that there's nothing stupendous we want to put in it. Maybe that big squad of footslogging VanVets with Ezekiel. If you want to make use of its Firing Deck, stick some Devastators with Grav Cannons in it and drive it to the middle of the table.

Razorback: B Tier: 6 is not a great number for transports, although that does get you a unit of 5 of something plus a character if you want. The Fire Support rule could be useful for a number of units.

Impulsor: C Tier: Not a bad unit on its own, but I'm not sure what you want to put in it. Perhaps a 5-man unit of Hellblasters, as you can advance the transport and then disembark. Maybe a squad of Intercessors since you can potentially flip a lightly-guarded objective that your opponent didn't think you could reach.

Drop Pod: A Tier: A full-on Drop Pod Assault list could be fun, although you are limited in what can go in one (at least Hellblasters and other Primaris guys can ride in them now). Maybe just three or so of them as a nasty first wave, followed by the rest of your army. Will need to test at some point.

Land Speeder Storm: A Tier: Putting a unit of Scouts inside for some drive-bys could be good against light infantry. Or put a squad specced for melee in and give them good threat range, although any Scout melee is going to be limited in effectiveness.

Stormhawk Interceptor: B Tier: If flying things become a popular part of the meta, these could be very useful. Otherwise, they are just a decent anti-infantry platform that can optionally take a couple of anti-tank weapons (that are only good against lighter vehicles.

Stormtalon Gunship: B Tier: This is the ground attack version of the Stormhawk, and it's probably better most of the time despite costing a little bit more.

Stormraven Gunship: C Tier: The flying brick is still a bit expensive, especially once you fill it with stuff. If you put it in hover, it will get focused down and killed, but if you run it like a normal aircraft, you won't be unloading the contents most likely until turn 3. Perhaps there is a way to make it work, and its firepower is decent.

Ravenwing Dark Talon: C Tier: It has decent guns, but it's way too expensive.

Nephilim Jetfighter: C Tier: Also too expensive despite having good weapons.

Hammerfall Bunker: C Tier: Probably terrain-dependent, and overpriced, but putting 6 Heavy Bolter shots into your opponent's units on their turn could be funny at least.
