depends a lot progamer also play BF series or quake on a low sensitivity, there (70cm 360°). U right about cs, its much more preaim than other.
Example Wltrs 90cm for 360° in a very fast game. At the end u have to decide what fits u. I personally think u have to select in every game a different sensitivity because the games are very different, in some games u can move faster in some slower etc etc....
and yea on the other hand there also high sens pros they can aim like gods, dont refer here to cs because as already said its more preaim.
But maybe also take in mind a extrem high sens or low sens will hurt ur hands!
