What a super-unfair question!
gonk I can't decide because each rendition of Squall is just sheer perfection (but then again, I'm obessed with him so it's not surprising that I'd think that.)
The only nitpick I have is actually about the Dissidia design but that's more of Tetsuya Nomura's fault because he's obviously a little blind (he said he based that outfit design off of one of
Yoshitaka Amano's images of Squall, but he totally didn't realize that the image Amano did had Squall with his jacket tied around his waist, not the little sash thing Nomura had tacked on). That's it, but I still think it's freakin' sweet anyway.
xd From what I know of, the redesign for Kingdom Hearts was supposed to be closer to Squall's original deisgn (he was supposed to look a little feminine but they told Nomura to change it ) thus the longer hair... No complaints there because it makes him look hawt.
whee I love all 3 versions but my vote's gonna have to go to the Final Fantasy VIII version because we saw that one first.
