apples and oranges? To compare a serve and volleyer (Mac, Edberg) who use their serve more like an aggressive approach shot vs Fed's serve who uses it for different purposes is going to be difficult. Also it's tough to compare as the top 4 guys now are all probably in the top 8 of best returners I've ever seen. And Fed has to play three of them consistently making his serve stats look a little worse than they should (and they are pretty good). I'd say Federer though, if you hypothetically gave him Mac's serve he wouldn't do as well. If you gave Mac, Federer's serve he'd probably be about the same efficiency wise.
