Nadal, Borg, Kuerten, Lendl are the only ones I would definitely put above them and maybe Wilander too. Bruguera and Courier are in the conversation of course but I don't think 1 extra RG makes up for Fed/Djok's better consistency and the nadal factor. Although I think on peak clay level Fed can stand up to Kuerten or Lendl and above Wilander. I'm one of the nice ones though. I tend to fall more on the side of "nadal screwed them" more than "the only reason they got to all the finals was the weak clay field". Both are true to some extent. But I do think it is insane to put Muster or Vilas above them for example. Courier has the peak level to hang with them, his RG peak was better than Djokovic's and similar to Fed's. I don't think Bruguera has the same top level. Vilas faced the same quandary they did except he never even came close to beating Borg on clay besides when Borg was 18.
So in short I think the top 4 is Nadal, Borg, Lendl, Kuerten in that order but after that there is a lot of room for debate between Wilander, Federer, Djokovic, Courier, Bruguera. Muster and Vilas are next and I think a guy like Ferrero belongs there too.
Appearing high on the list of best dirtballers is helped by the fact that so few of the games greats have prioritised it like grass - and by extention the quicker HC's at the USO.
