Who's the best PlayStation Studios/Worldwide Studios head? Phil, Shu, or Hermen?

I think it's too early to say for Herman, but I don't like Jim Ryan very much. His predecessor (Shawn Layden?) is a big reason why some those great games on PS4 got to go ahead, and Jim seems like a business man, not a gamer, but I could be wrong.
