Sampras has YEC, more weeks at No 1 , 3 more majors. But Nadal has the career slam, which is the "hallmark" of a true tennis great. Sampras was never a contender for clay, while Nadal was a genuine favorite in 2009-2010 on all 4 surfaces and he proved that as well. Rafa had genuine chances to win multiple majors on all 4 slams. Even Federer was not that close in this regard. Masters wins lesser said the better.Both have superior H2H amongst their peers. Pete ended with 7 wimbledons. I would guess Rafa will cross that at FO. I would give at least 1 or 2 more majors to Nadal by the time he calls it time. Even if he does not get to 14 majors and falls 1 or 2 short, I think he is the more "accomplished" player in terms of all round success. Any thoughts ?
