Going to go with Cheetor. Best of the available selection.
Movie Bee and Proper Bee are very different. I liked G1 Bee (well, Goldbug) in the comics, and he was always there in the cartoon, although I never had much of a fondness for him.
I have to say though, "the Wolverine" of TFs, at least in story terms is Grimlock. BB is more like a Spider-Man (although that might just be the voice making me think that).
