Roy Mustang

Voice Actor Comparison: Fullmetal Alchemist - Roy Mustang

Body: 

Something a bit less controversial:

Original Video - More videos at TinyPic
My pick: NO PREFERENCE, AS THEY ARE ALL AWESOME
Reasoning: If one bases Travis Willingham's Roy soley on his performance in Brotherhood (he was okay in the first series, but not great), he surely lives up to either Toru Okawa or Shinichiro Miki in his performance as Roy Mustang. All three are able to keep Roy sounding serious and authoratative, but with a little bit of cockiness, too.
Breakdown: Okawa = Miki = Willingham (Brotherhood) > Willingham (First Series)

Now TRY not to fuck this up, okay, commentors?
