At the very least Treyarch encourages Sniping.

IW on the other hand supports quickscoping, all snipers aim in reasonably fast, do insane damage (Barret has the same multipliers as a Bolt Action... fml) none of the maps are sniper/long range friendly other than Aground and the snow map which never pops up in multiplayer anyway, and Quickdraw effects Snipers while Sleight of Hand Pro in Black Ops doesn't.
