Russel is the best at getting to the end and all that. He is the best at the aspects of survivor we (except beer) enjoy, manipulating, social game, finding idols etc etc On the other hand, he will NEVER win. His strategy makes everybody hate him like cancer so he is guaranteed to never get more than 1 or 2 jury votes. He couldn't even beat 2 of the most lame players ever in s19. He could very well be one of the WORST players when it comes to winning.
Being good at a game means you are good at winning, the point of the game is to win and if you can't win, you're no good player.
So no, while Russel might be the best player at getting to the end, he is far from the best survivor player.
