Who is the true GOAT?

So just who is the Greatest of All Time in their sport, Tiger or Roger? I have to go with Roger if only because of his remarkable win loss record. Let's face it, this guy does not lose a tournament, he's won 35 of his last 50 tournaments compared to Tiger's 16 of 56. He's lost one match in 7 Grand slams, and that one loss was in the Finals of the French Open. Either way, right now we are enjoying the two best ever in their respective sports, its something that we should enjoy while we can.
