Battlefield 3 is way better than mw3 to me because of these things (and more):
More health:
Less first shot kills and more gun battles
Destructible environments:
Blow the otherside of the wall to kill some one hiding.
Blast your way out of situations if your trapped in a building or destroy a building on top of someone with a tank. Cant do that in gran turismo.
Team play:
Squad based modes for strategy. I drive tha tank or helicopter and you shoot ouot that shit
Vehicles:
Tanks, ATV’s, Boats, parachutes into the stage, #JetsGo lol
Better lighting and effects
Supperssive fire smokescreens, flashlights to blind enemies,
