I have browsed this forum for a few days and I see many of you now saying Nadal is now greater than Agassi. I totally disagree with that atleast at this point.
1 more slam does not overcome the huge tournament titles edge of Agassi. And Agassi missed out on so many additional slams by not playing the Australian Open for many years where has was unbeatable.
More importantly lets compare who is better on each surface:
Rebound ace- Agassi by far
Clay- Nadal by far
Grass- This is hard to say since they never played on the same grass. Agassi played on faster grass not as condusive to a baseliner, while Nadal got the luxury of playing on slower grass which is a dream to a baseliner especialy a clay court basliner like him. I believe if Agassi played on the same grass vs the same field as Nadal he would have done even better. If Nadal played on the same grass Agassi did against the same field Agassi did he would have done worse. So IMO it is Agassi but since we cant know lets call it a tie.
fast U.S Open style hard courts- Agassi
Indoors- Agassi of course, Nadal is hopeless here
Carpet- Just imagine Nadal on carpet when he struggles that much indoors. Yikes. Agassi by far of course.
Medium paced hard courts- Agassi
Nadal is hardly better on any surfaces. On clay and maybe grass, and probably not even grass. Agassi is better on rebound ace, regular paced hard courts, fast U.S open style hard courts, indoors, and carpet.
Agassi also had the better game. His groundstrokes are superior to Nadal off both wings. His serve and return of serve are both much better. And his passing shots and volleying are better. He also has better feel for the ball and court positioning. The only things Nadal does better is movement, overall defense, mental toughness, and arguably court smarts.
