This thread is pointless. They are 6 years apart and their prime was at a different time frame.
Unlike Fed and Sampras played in 2001, they are 10 years apart and neither of them were in their prime(particularly a 19 years old Fed).
Tier1(goat): Federer; Tier 1.5: Laver, Gonzales, Sampras, Nadal, Borg;
Tier 2: Lendl, Connors, Rosewall, Tilden; Tier 2.5: McEnroe, Agassi
