Like I said, defensible opinion and one that I don't have much problem with, though I would stick with Sampras.
He faced bigger guns on faster surfaces and still came away with a very good t/b record. Fed's t/b record is superior, but he has played on a higher number of slower surfaces, and against players who prefer to stay back. IMO, it's not a straight comparision.
