Great game ! But no Halo Killer to me.
The quality of an FPS is not in its music or graphics (fanboyism criteria..), but rather in its (perfectly tuned) multiplayer and that is where Halo 3 stands out (and lives...).
KZ2 has fantastic graphics, artwork, colors etc.... but even in multiplayer, it is more a COD4 remake than anything else. Without the class system, I wouldn't play it.
Ex: I was playing a KZ2 map tuesday. Some (tactitcian-class) guy managed to throw a deploiement grenade next to the objectif several times... it ended up in a confusing-repetitive-noisy-blood bath... 
Not the perfect example of a AAA multiplayer game. Such things never happen in H3.
Don't get me wrong, I really enjoy KZ2 a lot ! But it will never reach the quality and perfection (and fun) level of an Halo3. 
Evan Wells (Uncharted 2): I think the differences that you see between any two games has much more to do with the developer than whether it’s on the Xbox or PS3.
