Technically, the Treyarch games have always been inferior to IW games in terms of net code and hit detection. COD3 was considered terrible and W@W was sub-par as well, but they were eclipsed by COD4 and MW2. We haven't had that since IW got fired and we've been stuck with laggy games ever since...
I know everyone is entitled to their opinion and all, but man, How the hell could you guys possibly prefer 3ARC's games over IW's? I mean come on. The build alone of all the 3ARC games has always been inferior. The closest that 3ARC has ever come to having a build quality as good as MW2 was with BO2. And that took 3ARC two games to make.
CoD4 - Ok but not balanced well MW2 - Amazing, perfect gun balance BO - Boring, almost every gun was an exact copy of another one MW3 - Fun, good gun and perk balance aside from FMG-9s and the unpatched Type-95 BO2 - Amazing, perfect gun balance once again, most innovative in my opinion.
