Congratulations to David Cook!
As far as the singing goes, I'd say that he and David A. were fairly equal, just very different song types. But besides having a great singing voice,the one thing that impressed me all through the season with David Cook was how truely nice and down to earth he seems to be. Everytime the judges (or anyone) praised him for a song he sang he always seemed genuinely gracious with that little bow of his head and the folded hands. Love that quality in a person.
