Nadal is a dyed in the wool clay courter. A top spin reliant, high bounce favouring, lover of the dirt. His style is more suited to that single surface than either of those guys that you mention. The fact that this man has 6 majors (That's as many as Becker, as Edberg, as Budge, just one shy of the likes of McEnroe, Lacoste, and Newcombe) on other surfaces is absurd. Granted, accomplishing those feats is easier the past 10/15 years than it has ever been in the game's history, but still... 5 Wimbledon finals for maybe the most clay courtery clay courter that ever clay courted? Even in this day and age that's madness. He even managed to win Cincinnati, which until the 2017 revolution in Australia (a tournament he made the final of, and took to 5) was arguably the 1000+ pointer tournament on tour most favourable to aggressive, attacking tennis.
