Sampras was the greatest of his era. Federer the greatest of his. Nadal greatest clay courter of his era. Borg the greatest of his era.
But Sampras and Fed are close enough in time that it's not that difficult to compare their achievements and observe that Fed has surpassed Sampras on any surface and in any department.
