It will always depend on the game, and gamemode.
In single player I'll usually go for the sniper-ish approach with very accurate but slow weapons and headshot my way through, because bots are easy to kill on any difficulty setting really.
As for regular online shooters I only ever play BF3 online, and I enjoy most weapons, though shotguns and assault riffles in particular are favorites, but that might be because I tend to prefer smaller more intimate maps.
Only other shooter I ever play is Counter Strike, and thats purely for surf which I always do with a Pump action shotgun, being a low level player on an RPG server makes it the ONLY way to kill most players.
