Really depends what you need, with that kind of gear you are more flexible to drop some life. You can use that for more damage.
Rares are nice option, especially with banish procs or lightning arena, they get 400 life too.
At this point just experiment with gear, everything will work.
If you spec this set into sword spiral 0cd, you can stack 400mf and just farm duncraig with ease, fortress clears phys immune balls in every room, really comfortable farm.
