Fed Vs sampras

An ever lasting question... who is better...

well i am entitled to my opinion and i know the answer is Federer...

yes we should not compare players across generations... but if a comparison has to be made .......... it boils down to federer's overall game vs sampras serve n volley... i guess sampras might be best all time serve n volleyer..... but nobody plays the other part as well as federer and the makes him a complete player... the true champ...
anyway..
