The only good ones imo are Ken (It's Dante from Devil May Cry 3/4!), Dan (he has that goofiness that fits his character), and Seth (sounds badass!)
Everyone else (well Dan is one too but w/e, at least he fits his char) is an awful Funimation VA and they are all really bad! I am 200% sure Guile is Piccolo from DBZ. Also Bison is ok imo, he says "Now face the mighty Bison!" then "Bestow it upon me, and I may let you live."
The worst ones are Dhalsim, Akuma, Rufus, and El Fuerte. I bet you don't know what El Fuerte says either!! It took me so many rewatches of his section to figure it out.
