i prefer battlefield 3.it very awesome game ever.i collect a lot of point and i have a lot of superb weapon ever
Call of Duty definitely, i have almost all of them for ps3 and that's addictive online, i play for hours!
They aren't too games that can be greatly compared. BF3 is a tactical realism shooter and Black Ops is an arcade shooter. I would definately go with BF3 though because of the maps, guns, features, etc... Black Ops is way too repetitive.
I prefer both why? because when I get bored playing COD I go for Battlefield 3 and when I get bored Battlefield 3 I go for COD.
