"Once again, it's an incredibly close contest, but the Xbox 360 game comes out on top. With a slightly smoother frame rate, rumble support for all and two extra player slots in online games, the Xbox 360 game is the version to buy if you have the choice. Xbox 360 Achievements and an all-round better online service in Xbox LIVE are the icing on the cake."
Gamespot, IGN, Videogamer all give 360 as better choice.
