The Pro 900. Better detail retrieval, great soundstaging/positioning, and it single-handedly lays waste to the claim that you can't have great bass for competetive gaming. Not to mention that it runs just fine out of the DSS and Mixamp. I personally liked it more than the others mentioned for gaming, music, and movies. No regrets.

I had the opportunity to A/B the AD700 and the DT990 600Ω today with some games.   DT990 slaughtered it.
