Battlefield 3 or MW3?

I'm personally leaning a little more towards battlefield 3, the single player footage looked a lot more engaging then the mw3 video, but I guess it all comes down to the multiplayer. Somebody was at e3 was talking about the mw3 multiplayer being more tatical and balanced this time around, but I think that I'm still going to have to rely on battlefield for my multiplayer needs.
