I'm going with Tiger just because of the age defying aspect, and him just being the greatest to ever do it. The Rory masters I think goes down as the most exciting masters of all time from what I have seen at least. However, I think that the only reason the win is so great in the first place was because of the constant blundering that he kept producing. If he doesn't blow up on 13 this would have become a pedestrian coronation. Still the monkey off the back and still a tremendous feat to win the grandslam. However, it wouldn't have that legendary status that it does now.
