Also don't forget that Crowley told that: "Without a master plan, the Levis are just another monster. Hard to stomp, sure, but you love a challenge." They are like invulnerable and overpowered monsters. Even Meg killed 2 by her own. The thing is Leviathans are stronger than angels in overal but with the new information we gathered from 10x23, shows us that Archangels might be stronger than them and that makes sense to me. And yet we still need more informations about this topic.
