Cardinal Archangel = Deadly Sin Demon King

——

To put into perspective, a Deadly Sin Demon King's full power is equivalent to 666 newly promoted Demon Kings.

Most worlds lack magic or have very little of it, thus it is very hard for Angels of the Principality class and above to descend upon those worlds, creating the misunderstanding that Sparks are the whole Angel race and Enchants are the Archangels that lead them.
