If Holy Swords are Maou-class, it would be viewed as powerful as the Longinus already. Maou-class does mean God-class you know. The fact that Holy Swords aren't compared to Longinus is a sign that Holy Swords aren't Maou-class in power like you said.

Plus Holy Sword have fix output and abilities, unlike Sacred Gears which can evolve and even have subspecies, Holy Swords are actually very common only. It's powerful of course but only in hands of those capable of using it.
