Okay, the Multiplayer is essentially the same (bar the pace of it), so it's just a case of whether you prefer.

Treyarch (post-2008): Zombies, Short but on occasion enjoyable campaign, Slow paced but not too badly glitchy multiplayer, old weapons.

Infinity Ward (post-2008): Special Ops, Survival, Long Campaign which can flop at parts, fast paced but quite death-filled multiplayer. New weapons used today or a few years ago.
