Well in that case... oh wait, I guess I could say something constructive.
I don't play guard, but ever since 4th my main opponent has been russ heavy
IG. Seeing fewer than 2 russes in 1K plus games is virtually unheard of in my meta for
IG.
This edition hit the ordnance russes particularly hard as every gun but the main will snap fire, so generally those are best naked for their large blast. These are your
LRBT and demolisher.
LRBT is long ranged
MEQ killer and general
AT, while the demolisher ruins everything it can touch, should it get into range. Best to take these bare bones, and let them just snap fire the heavy bolter on the hull.
The non ord russes each shoot more, and excel at slightly different things. Exterminators crack light-medium armor and dakka
MC's. They benefit from hull lascannons for more
AT punch, but also sponsons a la carte for whatever your bane is. They are cheap for what you get. The eradicator is generally better off being a hellhound
IMO, but I would bolter boat it(bolter sponsons, bolter hull gun) if you want it. The punisher lays waste to
MC's and smaller units, best bolter boated. The vanquisher is all about cracking armor, and should always be fielded with a hull lascannon. Put it in a corner to snipe heavy armor. The plasma death tank, aka excutioner makes great use of plasma side sponsons for max plasma death.
Pask is good in any russ with a ton of shots, or a russ dedicated against armor/
MC's, so your vanquishers, exterminators, and punishers. He is still very expensive though.
