I saw Eden in Wicked, and her vocals were incredible.
Her acting, not so much.
She is not an actor.
She is a singer who says lines in between songs.
But boy, can she sing.
I happen to think Idina is a less extreme form of Eden, because I don't think she's that good of an actress either.
But that's just my two cents.
Personally, I think I have too much bloom.
