Federer and Djokovic both have 20 grand slams. I know that Federer is the sentimental choice because his style is so esthetically pleasing and because he used to be the GOAT, but Djokovic pretty much has him beat in all of the categories outside of grand slams, where they are tied. Djokovic has won most of their head to head matches, and he’s spent more weeks ranked number one.
So, so, long ago. Those guys were terrible players compared to modern players. I know that he was incredible for his era but I just can’t take guys like that seriously when talking GOAT status.
