Yeah, way to create ANOTHER thread about this, this thread will just become a battleground.

to answer your question; MW3, does it really need saying on the MW3 fourm?

COD4 what do I win?

I would have to say mw3. i don't really like battlefield that much. mw3 is really entertaining so i would recomend that.

Well, I like both but if I had to pick a favorite, it would be MW3 because BF3 has serious lag issues and have hard controls

MW3 hands down.  I don't like the way BF3 manages it's killstreaks or at least what I think of as killstreaks.  Too much time spent waiting around in the respawn lobby for a jetfighter or tank or something to come available and then you have to share it with the next person that hops in.  Lacks excitement imo but I do like the destructable environment.
