I do, too. I don't think there's a real star among this year's group, but think that Syesha has developed and improved the most over the course of the season. As a result, I think she has the most long-term potential.
I think Cook is probably the most saleable in pop music, and I think Monchichi appeals to the same tweens and young teens who like Disney's Hannah Montana, the Princess Diaries, etc. I think Brooke is too emotionally overwrought to withstand the rigors of a career in show biz. And I think Dreads has a cute face, a seemingly nice personality, but not much musical talent -- at least none we've seen on the show.
Something happened to Brooke because she was bringing it for "You're So Vain" and "Love is a Battlefield." She never recovered from the "Here Comes The Sun" moment and I'm still studying her to figure out why. It doesn't make much sense because it was almost like she went from a professional performer to this amaturish "emotionally overwrought" mess.
If you really watch her during You're So Vain, she is in the zone no doubt. So I don't know exactly yet what caused her to go all schiziod and nervous during her performances?
There would definately be a market there for her music/style if she could put it back together.
