curses/auras

I am at a point in my build where I need to choose between going for auras or curses...I'd run 4 protective auras. The main difference on the passive tree as far as final builds are:
curse build has 5 curse nodes, 10% more health, and blood magic node
aura build + 40% armor, 8% mana(will use blood magic gem for skills), +12% attack speed, +50ish dex an strength
otherwise the builds I'd use come out more or less identical.....I am a 2h straight melee temp.
I'm just struggling to choose between the added protection of auras with more health costly skills or the weakening power of curses...any advice?
