The best Power Weapon?

[Lord Krungharr]

For regular power weapons, I voted for the Lightning claw. Of course it nets 1 less attack, but the reroll on wounds is more reliably valuable. And especially on Khorne models!

Not sure what that Huskblade is but I wish Chaos could get those....

Well if we are including race specific power weapons, then the Huskblade AP2 Instant Death ftw. Closely followed by the Agoniser, 4+ Poisoned AP3 isn't bad at all.

I would like the agonizer a bit more if it actually counted as 4+ poison, rather than just 'wounds on a 4+'.
