I can only speak from the figures I own (Maul, Anakin, Obi-Wan, Qui-Gon, Aragorn... wait, wrong line, and Luke) and for me it's Anakin, by about a mile. I can see people's problem with Qui-Gon, but you CAN find poses in which the hair over the shoulder actually creates some movement and looks like he just flicked his head to the side. (yes.. I am resculpting my Qui-Gon, but thats not the point, lol. While he's up on my shelf I'm perfectly happy with him.)
I was not so with Anakin. I would say about 45 - 50% of the face is Hayden. The rest is somebody else.
But take note I'm not bashing the sculptor... I'm an artist so I know that when we look at our collective works some are looked upon better than others. For me the Anakin sculpt is one of the 'others'.
As a total line though? I'll let my hairy friend show my feelings
