I play 10 but sometimes in my first games I put 7 or 8 because I feel I don't have a good precision because when you first play you don't have good reflexes.. and when you do 1v1 the sensitive is way to high so you just loose it.. I totally agree when people say 5/6 for better accurracy but when I'll shoot you from behind you I will shoot one bullet drink a coffee and then kill you and you still didn't turn to see who shot you but inverse if you shoot me it takes me like a half second. To say all everyone has preference and nobody can say don't play on 5 because blablabla
