Well, if you just mean who is my favorite celebrity poker player I'd probably go with Negraneau because he is personable on tv or Ivey because, well...he's Ivey.
However, I initially took your post title to imply who would I like to be guided or coached by if I could pick anyone. In that case, if I could afford them and they were available I would pick someone like Dusty Schmidt or Andrew "Baluga Whale" Seidman. Fortunately both of these guys have made some great videos.
I saw some of Dusty's old stuff on the stox site and he does a great job of explaining things. I'm sure his DTB material is excellent also. I have been watching Baluga Whale's videos on Deuces Cracked recently and his way of explaining concepts really clicked with me. I was able to take things from his series and imediately use them in my next session. Of course he has also done a lot of writing on that other poker forum
Anyways, Dusty or the whale would be my choice for a "guide".
