It's Optimus Prime all the way for me! There are plenty of reasons to love the guy, but everything that makes him stand out for me is displayed by the "Megatron must be stopped... No matter the cost" sequence from Transformers: The Movie.

On a side-note, I've always wondered why so many folks hate Duke for being the perfect, poster-boy leader of G.I. Joe, but they love Optimus even though he's essentially the same thing for the Autobots.

(Not looking to start an argument here-- Just making an observation!)
