I enjoy the unhooded head look myself. Cassidy's Astonishing design is so streamlined and spare that the hood works well to go with the slick look of it. I can't look at that costume without seeing it as a statement though, in that he's down to an essential look and not draped with unneeded pockets and belts. I'm not crazy about Cassidy's design but I do appreciate him for opting for such a logical and true to the character design.
Gimme an unhooded Cyclops anyday. Not necessarily one with a lot of unneeded drapery, but a costume design interesting enough to go with that exposed head of his.
