Need a good math person to figure something out for me.

[Taimasan]

Ok I have a dillemia that I need figuring out because I kinda suck at doing math stuff, so was wondering if someone could help me out. Ok first off my strength is 20, I have The Holy Burst Ring(2d6 and +3d6 on a crit) and the Shocking Burst ring(1d6 + 1d10 on a crit).

My question is what is going to be better on normal difficulty against pit fiends?? My devout handwarps?? +2 Metalline(+15 damage a hit) 15 of Pure Good(1d6 a hit). Or my +5 Anarchic(2d6) of Evil Outsider Bane(2d6) -15 damage a hit??

EDIT: Forgot to mention my fists are 2d12.
