I prefer BF3 over MW3. I like the movement system better, i feel the gunplay is more solid, and i prefer the idea of having other players control the choppers, vehicles, and other things that would otherwise be controlled by bots who only trigger when you get a set amount of kills in mw3. I also think MW2 had better map design than MW3, mainly because the mw2 maps had more levels, while many of the mw3 maps are generally flat except for a few areas which have stairs to a walkway that goes a few feet. BF3 needs more levels in map design too, mainly because there are no catwalks or gangways in the default maps. catwalks and gangways are the coolest places to fight.
