Anyone saying controller doesn't matter is retarded. It's like arguing that a keyboard + mouse isn't superior at all to a controller (Hint: It is). If both players were equally as skilled then the advantage would go to the PC player.
That being said, the PS3 controller does not respond nearly as well to twitch reactions as the 360. I'm not insulting Sony's system, but there is a very good reason why Microsofts flagship game is an FPS
