Who wore it Better:Alicia Key or Mel B?

Alicia Keys wore this gorgeous contour dress which she paired with white soled pointed pumps (love those shoes). Mel B wore this to the X factor auditions days ago and paired hers with these georgy Versace babies. Its quite difficult to make a pick here, they both did justice to it but who do you think rocked it better?
