Best in being able to guard anybody one on one maybe, but Green is the best I've seen in team defense. There's a video where he guards all 5 players on 1 play.
As of right now I'm gonna go w/ the player that's won 2 DPOY awards. But there's no doubt Draymond's a damn good defender. I'd have him on my all defensive team.
