SAMPRAS
1990 US Open - at 19 took out #6 Muster, #3 Lendl (who had 8 consecutive US Open finals and was #1 until Aug 1990), McEnroe and #4 Agassi (French finalist and 1988 and 89 US Open SF losing to Lendl)
1993 Wimbledon def. champ Agassi, 3 time Wim champ #4 Becker, and Couireir (who beat 2 time champ and #2 Edberg in SF)
1993 US Open - easy for Pete as upsest opened the draw up, oblitterated Chang in last 2 sets and set aside Pioline (who beat #1 Courier)
1994 Aus Open - eaily beat reigning Rebound Ace king Couier in SF and Martin (who took out #4 Edberg in SF)
1994 Wimbledon - nothing special with Chang (on grass), Martin (who beat Agassi that year, and Ivanisevic (who had claimed Lendl, Becker, Edberg and Sampras on grass at that point played in a F and SF and would add Krajicek, Henman, Rafter and Fed contemporaries Roddick and Safin to his list)... Pete only lost a set and held 103/106 serve games (and 20 of 22 sets he played)
1995 Wimbledon Ivanisevic and Becker.... his 9.71 winner to every unforced error (68 winners to 7 unforced errors), highest ratio in slam final only to McEnroe in open era, and maybe all time (depending on records)
1995 US Open Martin, Courier and peak Agassi
1996 US Open -Ivanisevic and Chang (straight setted top 5 Agassi in SF) both at their best on hardcourts
1997 Aus Open -struggled in middle rds due to heat wave, destroyed top 5 Muster in SF and Moya (who beat def. champ #6 Becker and #2 Chang in SF) in 87 minutes
1997 Wimbledon - a soft draw with Agassi MIA, Rafter not blossomed, Goran... being Goran, but played sublime vs Becker in QF (70 winners, 10 unforced errors) and Pioline (aprrox. 45-50 winners, 8 unforced erors), held serve 116/118 serve games (incl. 97 straight)
1998 Wimbledon - P'sis, Heman, and Ivanisevic, even in his worst Wimbledon still held 116/121 serve games and put up 63 winners, 19 unforced (50 to10 after 1st set) in F
1999 Wimbledon overblown losing opening set to P'sis, that was the 1st he lost to Mark since 1996 (I believe), and blew away Agassi in F
2000 Wimbledon -severly injuerd shin in 2nd rd, was getting injections prior to matches, yet still held 118/123 serve games including last 85 (which he would extend breaking his own record with 118]
2002 US Open -beat #3 haas (at his best before all the injuries), destroyed Roddcic, and Agassi (who beat wire to wire #1 Hewitt in SF)
I won't even talk about the slams Sampras fell short in due to injuries. Take from it what you will, but I believe Sampras' road was harder. It just is what it is. If not just put each in the other's shoes.
