I played this game since 2011 and I personally believe the best player and the toughest one is latof, he's extremely tough yet skilled with unbelievable defense skills.
Basically latof was extremely good 1v1 and 2v2 (played Vs and With him so many times so I can tell ) no one ever since i joined xwis beat latof a single series (bo9) except marko and tim. Also he's unlike marko who sux at 2v2s. (99% of the players nowadays if you defeat their rush you'd pretty much win the game but if you could beat latof's desos then you would win the game)
that picture was in my mind until I saw The God " moon3 " and let's be realistic he's the god himself of this game IMO. just check out his videos in youtube.
there are moments in ra2/Yr where you can tell from observing some games that it's a 100% lose and then it's a WIN. Thats work for moon3
The bottom line is ( 1st moon3 , 2nd Latof )
