Believe what you want, I'm on both systems and my k/d is identical on both systems, and I maintained the same k/d without my go-to weapon on Xbox. There is no difference in skill level between the 2 systems as far as 99.9% of the player-base is concerned. And until you have the balls to link your account so everybody can see [i]your[/i] stats, I'll just assume you're one of the scrubs I own when I do play on Xbox.
