Here we go:
1. Michelle Kwan: Easily the most influential and decorated skater of these 20 years - not only was she the most successful competition-wise (5 Worlds, 9 nationals), she was highly influential outside of the realm of competitive skating. The most recognizable skater of these years, all disciplines included.
2. Kristi Yamaguchi: Epitomizes the perfect package. She did very technically difficult jumps - including 3lutz-3toes - but this ability was still overshadowed by Ito's even stronger jumping ability. I actually thought she was a greater technician than an artist (she was good, but not oustanding in that aspect). 2 World Championships, Olympic gold. She could have easily dominated the field had she kept skating until 1995.
3. Yu-na Kim: She still has a long way to go, but she already had an Olympic gold (the first lights-out gold in a long time in ladies skating) and a World title.
4. Irina Slutskaya: Most successful Russian ladies' skater of all time. She holds the record for most European titles and won 2 World Championships. Despite the fact that Sarah ahd Shizuka won gold in 2002/2006, Slutskaya and Kwan are the most dominant skaters from 1998-2006.
5. Mao Asada: Like Kim, she has a long way to go. Already holds 2 World titles and an Olympic silver medal.
6. Tara Lipinski: Like Oksana and Sarah, she may have won Olympic gold and then vanished. But she was a formidable competitor and strong technician, and she did have decent presentation, though it still needed to develop. Unlike Oksana and Sarah, she was fairly deserving of her World and Olympic titles.
7. Sasha Cohen: No World or Olympic titles. But her innovative spins/spirals and artistic ability are still well-remembered. A fairly recognizable name today.
8. Shizuka Arakawa: Her skills are on par with those of Kwan, Slutskaya, and Cohen, though she often did not have the consistency. But she pulled off good performances to earn a World and Olympic title.
9. Oksana Baiul: She did win a World and Olympic title - and was a strong artistic skater. IMO, however, she didn't deserve either title - they should have gone to Bonaly and Kerrigan.
10. Midori Ito: She may have won her World title in 1989, but her revolutionary jumping ability must be recognized. The quality of the rest of her skating was quite strong too. As Scott Hamilton said, her technical ability won't be beaten for another 50 years - and so far, that prediction hash eld.
Other skaters to consider (just suggestions): Nancy Kerrigan, Lu Chen, Surya Bonaly, Yuka Sato, Maria Butyrskaya, Sarah Hughes, Miki Ando
