1. Blanchett 2. Franklin (dead heat with Blanchett) 3. Gere 4. Ledger 5. Whishaw 6. Bale
Blanchett and Franklin were just so much fun to watch. Despite what appears to be the common take, I really appreciated Gere's segments (although they went on a bit long), and I feel that they have just as much weight as Blanchett or Ledger's. Speaking of which, Ledger is VERY good in his role but isn't given as much room to stretch his legs the way the three above him do. Bale and Whishaw are both good, but don't get as much screentime and thus don't get as much love from me. I really liked that Whishaw was basically a running commentary on the movie actually, but it makes him the most anonymous. And Bale is the one piece that felt the tiniest bit... well, not as exciting as the rest. I think that's down to structure more than performance, like all the others.
Ledger was sinfully uninteresting, Bale was just doing an impression basically but given the documentary like nature of his segments of the movie I don't know that it was a bad thing. Save for her last scene in the car I have always felt the same way about Blanchett, and given her scenes are not of the same nature (Don't Look Back inspired though they may be) I forgive it far less. I think Gere fit his part really well too, I don't know that the performance was as interesting as the story it was framed within, but I liked him.
The other two were awesome, and Whishaw's underuse was always something I held against the film.
