Aight I'll bite. From moving from the xbox to the ps3, I can say this: The ps3 version sucks in comparison.
You know before the match if you are going to have a good game. The trick is to not get host while having a great connection to the host. The faster your loading screen bar loads in, the better the game is going to be for you (unless your host). Of course that s*** never happens, so the lag does amazing things for you. Having the enemy seemingly see you a full second before you see them. The framerate is in no way 60fps. I can see the choppiness. After a death, the game lags so bad you can't even watch your killcam. And it takes around 3 square button presses to log in.
Basically the game is a joke on the ps3.
