I'm basing my ranking on how many times I re-watched performances from the competition.
Interesting that my favorites were National Championships, not international events. In nearly every case, one viewing was enough during the GP, Euro, and 4CC.
1. US Nationals. S/K short program to "At Last", C/J long program, C/B snake dance, Bradie Tennell short, Mariah Bell long, Nathan and Jason. This was a great competition.
2. Canadian Nationals, based on Roman Sadovsky. The rest was less memorable for me. The skaters I like best did better at other events.
3. Japanese Nationals, based on Shoma Uno. Very inspiring to see a young athlete bounce back.
