Deagle by a mile. At lower ranks where people stand still, revolver may be viable, but at higher ranks, if you miss the revolver shot, you're dead before you can shoot again usually. And you kinda have to camp/snipe people in pistol rounds with it, play peek-a-boo with them. So for CT, maybe, but for T where you gotta rush in to take a site, hell to the no. (Even Deagle is bad for that technically, but less bad than the R8)
