I have been playing GoW a lot lately on XBL, but I still prefer R6V. I think R6V is better than GoW in nearly all aspects. Gameplay is excellent. Good cover system, better than GoW's IMO. The graphics are great, sound is awesome (especially in the middle of a firefight when you have surround). Online play has a lot of options, and the more you play online (and do well), you'll unlock things for your custom character -- armor types, new weapons, etc. -- it's based off rank, much like BF2. You can also play the entire game co-op, but it does strangely remove all the cutscenes which drive the story. They've taken a lot of good elements from the SWAT series and made it better.
