90's were a weak era, Sampras servebotting Wimbledon and USO, but puking all over courts when match took more than two hours. Clown on clay, who used his fail serve and volley, when even a casual tennis fan you need solid topspin ground game not mindless net rushing and all or nothing ball bashing. RG in the 90's was as bad as it's on WTA today, every year new winner and not because of diverse field, but because of mugs stinking up the courts. One slam flukes like Ivanisievic, Krajicek and Chang making top 5
Washed up Becker, Lendl and Edberg Clownpras no competition at all, esp in late 90's except Drugassi who was winning slams until mid 30's, still failed to win RG because of one dimensional S&V game, got bageled by Clownfelnikov on clay
Tsonga/Ferrer/Berdych/Soderling > 90's players like Chang/Krajicek etc easy. Nadal/Olderer/Djoker >>>>>>>>>>>>>>>>>>>>>>>>>>> Servepras and Drugassi
Agassi is better than Nadal and Djokovic for now. He won all the slams in 3 different surfaces and when the surfaces were actually different.
