I think it's well established to most sane and reasonable people that Federer is by far the best player in the history of tennis. This thread isn't about who is second best, but rather who is better between Sampras or Nadal? Sampras leads in total slams, but Nadal has a career slam. So who is better? For me it's pretty tight. Total slam count is very important, but Pete lacking the FO severely cripples his resume. In a very close race I would give a very slight edge to Nadal because of the career slam. Thoughts?
