I'd vote CoD4, because MW2 was extremly unbalance and MW3, well even though MW2 was unbalanced I like it more than MW3, cause it just felt same shit I had seen in previous games.

Amazing campaigns? Are you joking me? Call Of Duty: Modern Warfare as a series is well know for having a shite campaign with little value. Everyone already knows that the games primary focus is it's multiplayer and the campaign is slapped together last minute.
FPS games with campaigns worth playing are games like Half-Life 2, Deus Ex: Human Revolution, BioShock, Metro 2033, Crysis, Resistance 3, STALKER... you know, good games.
You should play Borderlands, it has a very good campaign even thought it's usually called as Role-playing shooter.
