Well then, that's a BIG "IF".

I'm sticking to the reason that being closest to God gives the Archangels far superior grace that can overcome the Leviathan's overall blocking power or at least have a far greater resistance to it. It makes no sense for them not to - given their very nature and existence of their powers.

Besides, Michael, by all definition, is the ultimate slayer. He was built to destroy monsters like these. I don't think Eric Kripke would go that far out of the loop to portray Michael any differently. The Leviathans are Sera Gamble's mess to try to one-up the previous seasons.

Sounds logical to me.
