Peak for peak considering everyone and every surface.
Slow hardcourts- Agassi or Djokovic (Rebound Ace if it was Andre. He was the best ever on that surface IMO.. Plenty of material to look at 1995 or 2000 AO)
Fast Grass-Sampras or Pancho
Slow Grass-Nadal or Federer (Though I'm sure Laver would have his chances)
Clay-2008 Nadal or 1995 Muster (The two highest levels Ive ever seen on clay)
Fast Hardcourts-Sampras or Federer or Connors (I can't really choose between these three here.)
Indoors-Sampras, Federer or Becker (Too close to call respecting all three's peaks)
