Yes, if you are looking for tactics based play over shoot 'em up style, then go for BF3.

I bought both, BF3 on 360 & MW3 on PS3.

MW3 is frustrating as all hell to me, I just hate that the game is more based upon upgrades than it is about skill & teamwork. Games like this are weak online. The storymode however was great. BF3 online is awesome, big maps, greatly detailed and platoons/clans actually mean something.
