I have call of duty 4 for 360. the campaign is insanely fun yet challenging, but for online i would go with ut3. unreal tournament is one of the original online deathmatch games and provides a basis for most of the games today.
Reply:Haven't played UT3 yet (waiting for the 360 version), but I can tell you that Call of Duty 4 is one helluva game. The campaign is short, especially if played on the lower difficulties, but the online multiplayer is amazing. It's been a permanent fixture in my console since I got it.
