Never can trust those IGN head to heads They gave the PS3 the edge.. Prob cos of the controller more than anything, but they obviously didn't test the online enough.
Weird! Eurogamer gave the 360 the edge on their comparisons (really not much in it though, graphically), however I've had both versions and the online is leaps ahead on the 360. I reckon IGN just preferred the controller.
PS3 version has abysmal online since the championship update, it's truly borked!
