Agree'd. You'll notice there are alot of idiots on the Ps3 version of the game. I have both, and I can definitely verify without a doubt that the Ps3 is easier. I just prefer the Xbox controls and Xbox overall xD. However I still go 39-4 every game on the Xbox xD.
The compertition is ALOT more fierce on the xbox imo, but the control's are alot more friendly for my hands. I have both but preffer the challenge on xbox. Its just a more competitive game console in general I find.
