It's not about how strong an angel is. It's about how much experience and knowledge they have under their belt. Around wiki, it's called Cosmic Awareness. The archangels are the only ones to see and interact with God in his true form. Having an unparralled connection like that which easily correlates with experience and knowledge leads me to believe that the archangels at the very least possess a far superior resistance to the leviathan's negation ability.

Why, you may ask? It's real simple, the archangels's source of power is from God himself. They are his closest creations of all. Henceforth, He gives them the greatest amenities and top priority over all.
