It's very clear that youre biased towards Vitality, this topic i can judge objectively since i was never fond of Kenny and ive been giving him shit lately.
Zywoo isnt nearly as skilled as Kenny was in his prime. Also Zywoo' s playstyle and focus points are much different and thus you cant directly compare their peeks, but for me Kenny was the better player ( you can only do it by rating, but it doesnt tell the whole story )
Kenny at his prime was just way too skilled and fast, Zywoo on the other hand is around average mechanically ( even olof said it in a interview by betway ), Zywoo plays the game to perfection, he also has a very good reaction time and he knows how to use it but the main focus of his game is his position and read of the game.
Also NiKo is more talented than S1mple. Shox, F0rest are more talented by him too, S1mple is very talented but not on their level, s1mple is like cr7, the biggest hardworker, he literally has 7k more hours in csgo than Shox for example, 2x as much.
