Which Elphaba performs "Defying Gravity" the best?

Question:Why?

Best Answer - Chosen by Asker: Why?

Well, they're all really good at it. I don't think just one of the Elphabas is 'the best', I like all of them. Eden has(well, had) a lot of power and emotion. Willemijn Verkaik (Vil-ah-men Fehr-kike) is the Elphaba of the German cast. She has an amazingly consistent voice and could, and can, give all the other Elphabas, past and present, a run for their money.

This is from the German cast of Wicked: Die Hexen Von Oz(the witches of Oz) performing One Short Day (nur ein tag) and Defying Gravity (Frei und Schwerelos) on the tv program "Wetten Das???"

I think Idina Menzel was the best at "Defying Gravity". I'm not going to sayu that vI dislike the other Elphaba's, becuase I do not. I think Idina was the most emotion, passion, and strength for "Defying Gravity."
