I think most agree that comparing Federer and Nadal's achievements since each won their first Grand Slam is unfair to Nadal because Nadal won his first Grand Slam at a very early age.
I think it is more fair to compare their careers since first becoming #1.
Looking at the average ranking of the opponent they lost to in Grand Slams from first becoming #1 to last being #1.
Federer - 2/2/04 - 11/4/12
30, 4, 5, 2, 2, 3, 2, 2, 1, 6, 7, 13, 3, 3, 1, 19, 1, 2, 1, 7
Average = 5.7
Nadal - 8/18/08 - Present
6, 25, 6, 4, 7, 2, 1, 1, 100, 135
Average = 28.7
