I always go with the shotgun.
In my opinion, anyone can pick up a sniper rifle and put an instantly lethal bullet in an unaware target without fear of retribution...that's easy.
It is considerably more difficult to have to run from one side of an open map to the other while dodging sniper fire, rockets, grenades and other shotgun/smg weilding players along the way to deal with some camping sniper tucked away in some dark corner, only to be blown up by a concealed landmine or no-scoped (meaning you have to go through all of that again).
It is provably more difficult (especially in recent times) to go for CQB than to snipe but in my experience...that extra challange makes me somewhat better.
