More (unpainted) Khorne Berzerkers?

 Trying to take advantage of the "forced" motivation from a soon-to-start painting competition over at the Relicnews Painting & Modeling Forum, I'm putting up my long-untouched Berzerkers on the block as an entry to try and get them done. Most are glued and have the detail work finished (scars, scratches, chipped armor, etc.), but a few are just held together with putty for posing purposes and still need some love.

The rogue's gallery in question:

 They are a mixed bunch, with one inducted former Space Wolf (wolf-head backpack not pictured) and the stand-in for my Skull Champ w/ Power Fist (he'll be demoted eventually, when I finish a planned conversion, but does nicely for right now) - the rest are more or less straight-up "vanilla" Berzerkers aside from some conversion and reposing. With these guys done, that'll be a full squad in play for my Disciples of the Four, with the Slanneshi Chaos Lord from the last update leading them at the front.

Relative Killy Virtues of CSM Power "Stuff"

 Apparently by trying to tweak my CSM Codex-standard 500 point army list a bit so far as the retinue of Khorne Berserkers accompanying my Undivided Chaos Lord into battle, I seem to have hit on a very polarizing topic in the community under 5th Edition Warhammer 40K rules: the relative killy virtues of Power Fists vs. Power Weapons.

 The scenario is that my Chaos Lord and a smallish number of Berzerkers (say, 5, one of whom is a Skull Champion) are piled into a Rhino APC to rush across the battlefield, pile out under cover of smoke grenades and supporting firepower and then run at a charge, howling for blood to be spilt and frothing at the mouth with maniacal anticipation.

 All things working out as planned, so the Berzerkers have Furious Charge with a bonus to Init. and Str. and an additional Attack for initiating the assault. The Chaos Lord does his bloodletting, but let's assume that there are more than enough warm bodies with pulses still standing for the Berzerkers to have their fun.

 Now if I'm understanding correctly, if the Skull Champion had a Power Weapon he would get all his attacks at a slightly higher Init. the first Assault turn, get a bonus Attack for the pistol in his off hand, an extra attack for the charge, and any hits would ignore enemy armor saves. A lot of potential hits at better-than-MEQ Initiative, in other words.

If I tooled out the Skull Champion with a Power Fist, however, he would attack with a 10 Str, get an extra attack for the charge, and cause
Instant Death to MEQ's. The down side is that in current 5th Ed. rules he wouldn't get an off-hand weapon attack unless he had another Power Fist, a Lightning Claw, or something similar. Oh, and he'd strike dead last in Initiative order with all his Power Fist attacks - there's not much point in saying he'd use his Bolt Pistol for all his carnage just for
the sake of running with a higher Init. since that kinda defeats the whole point of having him assigned a Power Fist, you can't split Assault attacks between weapons rules-wise, and the Fist is so much more intimidating.

 With only 5 Berzerkers and a worst-case scenario, the unit might all be dead before the Champion is even able to get medieval on the squad's intended victims with his Fist. Myself (being an absolute novice player), I think it would make more sense to have as many attacks at as high an Init. as possible and be able to cut through armor like butter. Judging from what I've read on various 40K-related forums, the majority opinion favors Power Fists versus Power Weapons.

 What do you folks think? I'm wondering what would be better for my small CSM force-in-progress. So far as modelling, I've got either extra-killy Power "stuff" option covered with a planned conversion for my Skull Champion.
