i agree w.a.w. was the best of them all, however for the question at hand... MW3 was made by infinity ward, so we know a few things: 1. They cater to the "average" player, in other words people who only play 1-2 days a week. 2. This is why there is lag comp, and death streaks. 3. IW makes the most crisply visual call of duty games. 4. Finally the customer service at IW is non-existent due to fact #1. BO was made by Treyarch, and thus tells us a few things: 1. The customer service is decent 2. while the graphics are not as good, the gameplay is much more stable, and they maintain their servers much longer than IW. I believe that treyarch is a much better game maker that needs to work on polishing their graphics a bit. Therefore i believe that Black Ops was a much better game than MW3.
