Neither. Stone arrow, blighter, or anything with auramancy or witchcraft. Defense tree coupled with DPS trees are going to give you survivabilty without sacrificing damage. Anything with auramancy or witchcraft is going to let you regen faster and give you utility for long grinds. I typically grind a stone arrow, demonologist, and darkrunner. They can go for hours without any help from me. I typically only die if I get ganked.
