I could not choose against Henson because he was Kermit. He originated the character, he performed him and defined the character we came to love.
I could not choose against Whitmire because he took up the huge, daunting task of following Jim's act, and stuck with it, and has kept improving to the point that now I don't see Jim's Kermit, or Steve's Kermit, I just see Kermit.
That which exists is greater than that which does not exist. Kermit exists in both their hands. (Or on their hands.)
