I think every single member is well designed (look, boss design and personality-wise) besides Marluxia (sorry, his fans ) to a degree that they always were one of my favourite parts in the series and video games overall. Maybe it's because they appeared quite rarely and they were always wrapped in that mysterious and serious atmosphere, and you always knew the s*** is going to get serious when they appear, but anyway my fav are:
-Demyx (a guitar weapon with original attack design? A likeable user not because he acts like a boss? take me!)
-Lexaeus (had to google his name... EVERY. SINGLE. TIME. I mentioned him anywhere (had to say this) Not a big fan of his personality or weapon design, but DAMN, the fight(s) against him in 2FM was insane! Also, in the japanese version he is voiced by Zaraki Kenpachi, so... Easy choice)
-Xemnas (I like how intimidating this guy is during boss fights, although he is pretty easy outside 1FM... Also, his english voice that can shake even a straight guy's crotch)
-Saix (his fighting style and design, and screams are pure badass)
My least favourite are:
-Marluxia (big confidence+zero personality=a no no from me)
-Vexen (this guy has a punchable face and I dislike the nerdy-evil-scientist type of characters, especially if they have slow but tricky fighting styles)
