If fed was playing in the Sampras/Agassi/Courier/Edberg era, I don't think he'd have even half the number of grand slams he has now. So, from that perspective, I'd go with Edberg.
However going on numbers alone, federer is the obvious winner there.
lol Emme, fed played 1 match against Sampras so he played in their era, how right!. So, how many GS did Sampras win after that? 1, before that he won 13. Yea, right he was playing in their era. And, do u know the meaning of whooped? It's what Fish did to Fed at Indian Wells. Oh but your a 10 yr old girl, sorry such words must be pretty hard for you to grasp. Anyway's in that so called whooping that fed gave Sampras, he BARELY won the match, in 5 sets. So much for your whooping and your fool comment. DOLT DOLT DOLT!
