I see a lot of threads trying to diminish Djokovic's year. He was literally one match from winning CYGS, and I think people don't seem to care about it, because their fav players didn't compete in this edition. I don't really care about that, but something occurred to me. I can't really think of one really strong USO in last decade (not entertaining, or competitive, but one in which 3,4 top players brought their best game to tournament). This year I think only Med checks the mark, last year literally not a soul, and this stretches all the way to 2009/2011. In your opinion, quality wise, which USO was the best one, or to change narrative, best GS tournament of each(AO,RG,W and USO)?
