I've been playing sunbreaker a lot and it's actually pretty awesome. The burst healing is so great and probably the best lock PvP super. I roll with devil's and urielles. Arc is probably the best though, good super, good nades, extra damage on rifts, just all around good. Void is terrible for PvP I recommend avoiding it. Super isn't very good other than if they are all grouped up, you likely won't get enough kills for devour to be any good, and unless you're able to secure all the heavy ammo for your sweetie blink isn't much use either.
