I have modern warfare 2 for both systems and on ps3 i tend to get a lot of kills and kill streak but on xbox its like i'm sucking really badly and cant hardly get a k/d ratio.

the graphics on the ps3 are more basic and the xbox 360 r high def ooh the controller is the buttons are different instead of letters its shapesX (triangle),Y B,(square) forgot other one well yeah.... oh and circle but the knifing n stuff on cod is the same

Well, the controls to me are pretty much the same (the location of the buttons is very similar). For me the xbox360 took some getting used to seeing as I own a ps3. The main difference I would think is that the xbox is a little more choppy and blocky compared to the PS3 (seeing as the ps3 is a bluray player and the xbox is only an "HD" console" and that the PS3 has alot more power behind it). The xbox lags a little more than ps3, not only according to me, but according to my friend (who is a halo fanatic).

Hope this helps ^_^

that could go two different ways. Xbox live is more competitive because there are more people on it...mainly because it cost money. Now I've heard that statement, but I've also heard that the layout for the PS3 is fairly easy to adjust to and handle better than the more bulkier controllers of the Xbox. I don't own a PS3 but I've heard those arguments before. I'm an Xbox man myself. Happy hunting, unless your against me.

From Many personal experiences from many different people the PSN community is less skilled and more relaxed/ casual people than LIVE
