Who won? MK. We all know that.
Who deserved to win? In all, I would say in terms of SKATING, Cohen was the best.
SC was clearly the best in the first round, IMO. However, had Alissa not fallen, it would have been a little more close between the two. I wasn't surprised MK was ahead by such a margin, though, and no one else should have been.
The second round- I thought this was a tough one, actually. From my point of view, you had Cohen who skated very well (but was kind of bleh), and MK, even though she struggled with the jumps throughout, I felt really sold the program. Of course, this is me watching the program on my 2.5" camcorder LCD screen, lol. It might have been different if I was watching in a theater or part of the audience.
I actually gave the nod to MK. Why?
Don't get me wrong, they were both good performances. I've seen Kwan skate better than that, and I've seen Cohen skate worse than that.
Here's how I do it:
Cohen: Good skate. I didn't get that feeling of emotion that a lot of other people (including the judges) seemed to feel. I just did not like it. BUT, she did hit all the jumps. I also thought that "ending" was rather jarring, and that took points away in my book.
Kwan: It's understandable that she would be working out some issues like jumps, etc. I think she got into her program more, though. I could feel some "warmth" in that performance.
Now, this is "tough" because I could have gone either way. As to who the better SKATER was, it was Cohen overall. As to whose program I enjoyed more, it was MK's. I gave the nod to MK to win THAT PARTICULAR ROUND. So much for objectivity.

But this is audience vote, right? I knew MK would win either way. My little vote wouldn't count
Factoring in BOTH performances, though, I feel that Cohen probably should have won overall, since she skated better. But since these were EXHIBITIONS, I decided to go with the performance I ENJOYED the most, rather than the one that was skated the best. That's the way I saw it.
If the audience were judging competitive programs, then I would go with the one that was skated the best. (In the first round, SC did both, I feel- it was enjoyable AND she skated it well.)
My rather controversial 2 cents.
