It's hard to make a TOP list, but I think s1mple is probably the best at the most aspects, he's lightining fast, he's also good holding, looking for picks, making plays, entry kills, etc.
Device is also good, but he's a very different awper, he has absurd timings and incredible positioning/patience when holding, picking the right time, but yeah, he has by far the best team sourrounding him.
GuardiaN is good, consistent, sometimes he makes bad plays, he relys too much at awping which is bad sometimes, but he's good overall
FalleN used to be the best agressive awper in the world by far, his mechanics and movements, risky positionings, insane fast flickshots, etc made him an awper so cool to watch, but he's so off right now, he seems like he lost confidence, his timings are off, every single time he puts his crosshair away, he gets backstabbed, he's bad at holding as well, very unpatient awper, but I think he can be back, mibr looks very motivated
Gratisfaction is very new for me, i've never watched him before major and he's pretty good, fast, consistent, he doesn't fear and he has not any hesitation when picking which is very nice to see
kennyS for me is like FalleN, very shaky and looks very unconfident and like GuardiaN, relys so much at awping, there are games I watched he was like 2/12 and picking awp every single round, wtf, play aug or ak, you might get some kills and help your team if awp isn't helping
allu, I always liked allu, he's not fast but he hits shots, very calm, sometimes unconsistent, but he looks like GuardiaN rn, for me
