I think with Nadal, a comparison is really futile. He seems to be on a level of speed where I cannot say that Sampras is faster. He is more or less just as explosive as Sampras AND more enduring. Federer is also superior in endurance, but not in speed, acceleration, hence why it's not crystal clear with him.
So who's got more power? Federer or Sampras? (just please don't tell me that Sampras' serve was 15 mph faster than Federer's cause that's a lie)
Just shows you how pointless H2H's are. Nadal beat Fed but in the end it meant jack, they both walked away with nothing. It's about winning titles.
