Discuss. My choices are:

1. Yuna Kim

2. Savchenko/Szolkowy, Virtue/Moir (tied)

Being respectively four-time WCs and Oly champs, they have incorporated so much difficulty and originality into their programs without harming the essence of the respective disciplines.

4. Mao Asada

Thanks to her star power figure skating has enjoyed unprecedented popularity in Japan, with the emphasis on her beauty, a 3Axel and the rivalry between her and Yuna Kim (legitimate or not). Despite her weaknesses the current scoring system heavily penalizes, I'm inclined to think her presence and her skating are special enough to be remembered among the greats.
