Simply put. Regardless of how strong you are if someone is immune, Ex. (leviathan to angelic magic) or is able to cut off you off from your power Ex. ( Eve unplugging Cass from his power) it's a mute point. But, as there is no case of Archangel vs Leviathan it's a rough description. Only facts are these, their older than all angels, can unplug or is immune to some if not all angelic power, and in case of Leviathans said that they can kill Angels, according insane Cass.
