It depends. If you seem to like games like Gears of War, Halo and don't like GT and prefer Forza go for it. But if you want to buy it because of the muliplat games just keep your PS3. No matter what anyone says they are the same. The graphics and technical issues are usually the same they both will have the same amount of people playing online. But if you dislike the PS3 controls from games like COD, Madden and Fifa and other big multiplat games you enjoy 360 will be right for you. I personally love both PS3 and 360 controlls and I find 360 better for FPS and sport games and PS3 for everything else including exclusives.
