My personal order:
Kristin
JLT
Megan
Kendra
LBB
I love Cheno-squeak. She was so cute in the role, and JLT does have a deeper character, but it's needlessly deep. Some of it is good, but some moments take away the light-heartedness of her character.
JLT was good, she did bring depth to Glinda, made her a much more round character. But you can't compare her to Kristin's singing.
Megan was okay... when I saw her she was still relatively new to the show, so she wasn't used to it yet. She did well, though. I bet she's better now. She has a nice voice. I liked her "For Good" and "Thank Goodness" and "What is this Feeling?" and most of it, but I disliked her "Popular" very much.
Kendra, well, she was okay. She managed, and she did it well, but not as good as Cheno/JLT/Megan. The whole tour is worse, in my opinion, than the B-way production. I don't really like Shoshana or Stephanie, but I think Shoshana is better, same with all the roles.
I HATED LBB. HATED HER. She didn't seem right for the part... I didn't like her portrayal, at ALL. I only saw her in it once, thank goodness.
I never saw Stacie.
We can't all come and go by bubble...
