What was the more impressive feat of GOAT slaying - Safin or Krajicek?
Richard Krajicek defeated Sampras in straight sets at Wimbledon 1996 (Quarter Final) on his way to the crown.
Marat Safin defeated Federer in five sets at Australian Open 2005 (Semi Final) on his way to the crown.
Both Sampras and Federer were arguably at the peak of their powers. Krajicek was not really considered as one of the favourites as he hadn't gone past the 4th round previously, while Safin was one of the favourites. Krajicek won without too much trouble while Safin showed great resolve, saving a match point. Krajicek went on to defeat Malavai Washington in the Final, Safin defeated Hewitt.
Which victory and subsequent tournament victory was the most impressive?
