I think Kimmie is better at 16 than Sasha was at 18. At 19 Sasha showed me that there was more to her than flexibility in Dortmund. However, she continues to be eratic and I think we are all waiting for that wishful 2 clean routines.
Kimmie is still a work in progress. There is a budding lyrical style and I think a season of COI will bring her to fruition.
I think the two ladies in question can be compared competitively but I would say Sasha has it all over her in show skating.
