Imo claw, g3mini and ch0pstyx are best, adam-w slightly behind
players like thumb$ and poiuyt were getting there, but switched to gow or stopped playing
I did not mention player because he sucks horribly in 4v4/3v3, maybe even in 2v2. 1v1 is his strongest match-up due to general speed and war2 knowledge, not chopping-skills. It showed in a 1v1 tournament when i played the finals vs him (we were pretty close to each other every game and i put extra emphasis on early and mid-game pressure due to his weakness). Not sure if replays are uploaded.
Still though, if we're only taking 1v1 into consideration then he should be put on the list
