Best Tennis Match in the history of tennis

I consider this tennis match between Pete Sampras and Roger Federer the best tennis match ever played. I watched this several times already and still the tactics used by the two adversaries are the best strategies in tennis. This was the 4th round match at Wimbledon 2001. Federer won the match but I expected Pete Sampras to win since Federer was not at his prime yet. Federer just bloomed and developed his game in the year 2004 when he began beating top players. The court aspect maybe an issue or perhaps the will power to win since both of them have the same strategies. This match is a battle at the net and the advantage of control or attack.
