Fed Rulz, I do agree Fed and Nadal's overhands are devestating, I think Fed is great and has alot of variety, Nadal's is more devastating a la Sampras. Also, whoever says Nadal doesn't have touch doesn't pay attention, he does indeed look extremly awkward and unnatural at net, but suprisingly he does volley extremely well for someone you would expect to be terrible, and makes many more difficult volleys than people want to give him credit for, personally, I think if he could develop this aspect of his game and be even more willing to use a net game as his tactics, with his lefty hook, and monster forehand, it is an unstoppable combination.
Sampras seldom missed, and also hits many leaping backward overheads from No man's land, well past the service line, even hitting the slice variety. I actually think his overhand is second to none, and his overhand from the baseline is amazing as well, you can see Federer use this shot alot as well.
Personally, my favorite overhand of Federer's is his slice "inside in" overhead,he hits it often, and its so deceptive, he even hits it off pace, and inside out.
I think this is close, as they all have strengths in each of there overhand, to me this is a "pick em" category, where you really don't have an wrong answer with either of these....but I would go with Sampras because of his style of play, he tends to hit more overhands, more often. Hence his opportunities to even hit as many brutal slam dunks...or you could just say I am a moron Pete-**** or whatever you variety you come up with today
