How to socket Mjölner?

I have a nice Mjölner with Volls Devotion, alphas howl, aegis etc.
But i have no idea of theorycrafting. I cant post the char because this is my 2nd forum account and the mjölner char is linked to the 1st one which has been closed during an transaction.

my question:

mjölner socketed with Arc+Discharge+Ironwill (all lvl 20, 10%Quality) + Maligaros gloves


compared to


mjölner with Arc-Discharge+ Elemental Focus and Repentance Gloves.



what would u prefer? i cant check the damage output of discharge and arc so i need some theorycrafter.. :(

repentance seems to improve defense with aegis, but what happens offensively?


tx in advance
