Grrrrrrrrreetings!
So, I've been browsing through my Dark Eldar codex, and I've gotten reached the point where I'm messing around with Heavy Support options, outside of just having three Ravagers. Looking into the two fliers, they actually seem quite interesting, though I can't see myself fielding more than one. Specifically, the Voidraven Bomber caught my eye first: the sexy Void Lances in particular. However, I'm caught between which of the two fliers to really delve into.
Razorwings only have two Dark Lances and 10 armour all around, but come equipped with four Monoscythe missiles base, and can be upgraded with a twin-linked Splinter Cannon (not that that this really interests me, but it's something).
Voidravens make up for only two lance weapons by having those sexy Void Lances (Strength 9 AP2 Lance weapons), have 11 front and side armour, comes equipped with a void mine from the get go, and has exclusive access to Implosion Missiles. However, they need to purchase any missiles they may want to field as they don't come with any base missiles, and I'm not entirely clear on how effective the Void Mine would be due to the percieved unreliability of
D6 scatter (with no
BS subtraction).
Missile options also affect this decision. While the Voidraven has a total of four missile choices compared to the Razorwing's three (including the missile type the Razorwing automatically comes with), the Razorwing can upgrade its missiles for half the cost of the Voidraven's missile purchases. In other words, I can equip the Razorwing (or more specifically, replace it's four monosythe missiles) with four Necrotoxin missiles for the same cost to equip the Voidraven with two Necrotoxin missiles. At the same time, I'm uncertain how much of an upgrade Monoscythe to Necrotoxin would be. It's effectively moving from wounding a lot of stuff on 3+ and others on 2+, to wounding everything on 2+. Does this justify the cost? The stats for Implosion missiles are great, though I'm put off by the smaller blast template, plus the hefty price for a single-use item. (Just to extrapolate, I'm coming into Dark Eldar from Orks, so my perception of single small blast templates is admittedly skewed

)
Both vehicles cost the same, and I'd be naturally inclined to give both of them Nightfields and Flickerfields. The price difference falls down to missile choices.
SO! I'm curious as to the communities perceptions and experiences with either of these vehicles of war, both the positive and negative!
Importantly, though, I'm specifically investigating the comparison between these two vehicles - I'm fully aware that either choice competes with Ravagers for Heavy Support choices, and I know many players would be quite emphatic that I should just use Ravagers and ignore the fliers (or any other Heavy Support choice) - but I'm not interested! This is purely about the Razorwing versus the Voidraven!
I'm also not really bothered by cold and callous competitive environments. Though I'm just as interested to hear viewpoints of those who work towards such army builds, I'm quite happy just to hear general thoughts and experiences of casual players, anyone who's tried it out, or (for those who've not played with/fought against these vehicles) what people think based on the vehicle stats or what I've said above.
