I really can't figure out the context to advise you in. If you're talking tanking, you could get more effective health out of the new gloves however down the road it would be replaced by your tier 10 gloves because gloves is one of the four slots a tank uses set pieces in. If your talking DPS it may net you a small gain currently, particularly on mobs that die fast as the rip bonus only really matters on a longer fight. On a longer fight however the set bonus may yield slightly higher damage from more crit.
It's very difficult to figure out what your priorities are because your gear is all over the place. You're half gemmed and enchanted for DPS and half gemmed and enchanted for tanking.
