I think that Reuben will be more marketable. Honestly, Clay has the look and voice of a Broadway performer. I think he will make it on Broadway whereas Reuben probably doesn't have a chance on Broadway. I think Clay will win anyway.
I heard or read somewhere that Frenchie Davis is now starring on Broadway in the show "Rent".
I've been trying to find an article to post on this but so far have been unable to locate one.
