I liked Anna Rechnio's short program to GWTW at 1998 Worlds, but that was more due to the all-guns-blazing quality of her performance (she finished 2nd in the SP to Michelle Kwan there) rather than anything special about the program/choreography itself.
My mouth was agape (in a happy way) when the ShibSibs' FD scores came up and they took the lead. I got to see both them and Chock & Bates compete in person at Skate America a couple seasons back, and while C&B won, the Shibutanis got by far the bigger ovation. Their connection to the audience is that much stronger.
I actually like Ashley Wagner's skating; I feel she's a far better performer than either Gracie or Polina, although I do think technically she doesn't quite match up to the other two, especially in terms of jump height and rotation. I wish though that Ashley would do a little less self-promotion/trumpeting and just put down solid, consistent programs on a regular basis!
