I like Squall's 'cause of the Griever embellishment on the blade and the matching icon on the chain, but these make it look cumbersome and a bit cluttered. Seifer's, on the other hand, is relatively plain, but perhaps this is what gives his gunblade a more serious initial reaction. Also, the angles near the hilt of his weapon are more prominent, giving the semi-arc of the blade an overall sharper and deadlier appearance.
