Depends on the game. I'll usually rock a sniper cause I find it more fun and satisfying to ohko from a distance than running around shot gunning. It's all down to your play style. Like for trials, I usually snipe and my other 2 shot gun because I tend to be the better sniper out of us. However sometimes we would play kids who rush all over the place and snipers aren't viable (well if I could consistently 1 shot to headshot kill them up close it would be) so I'd run a shotty too. It's a situational and a preference thing.
