i think its different dependant on play styles, sensitivity etc.

as a player whos used the awp quite a bit at times and a hater of it it is way over powered peeps say its not an insta kill but in mid and less range u cn shoot someone in the lil to at full helth with armor n u cn kill them ( iv used it at times kill 50 od shooting only 40 shoot n basicly no headshots), the awp is also much greater efected by lag and if ur laging much u tend not to even hit a stationary target that u spent a seconds lining a shop for a perfect death. though both sniper rifles are to slow for my play style i like to av another bulet in the chamber as soon as i fire the last 1 lol
