It depends on what kind of play u like. If you love the net-play, Samparas will most likely be one of your favorite palyers. To me, he is the best.. I simply love that man. I know that Federer will surpass Sampras' 14 grand slam record (if he stays fit for few more years- he is just 25 now). But till then, lets respect the records no matter what kind of play you love. Till then, Sampras is the best palyer. Bjon Borg was very great player but he cut his career short.
