Federer has won more % of points on the 2nd serve than Pete (though I remember someone questioning that stat because of the way ATP kept their stats in the early 90s).
I interpreted important moments as being high-pressure moments (later stages of grand slams, for instance), and Federer clearly has had more of them than Pete.
if you want to compare federer and sampras here is an intersting article.
i still think sampras serve was better than roddicks. those statistics may be similar but sampras was a better clutch server and sampras played better players more often in bigger matches
