OH. MY. Gosh.

No, Archangels ARE stronger. For one, not one of Vulnerabilities of Leviathans would work on a Archangel, e.g. beheading, Witch's spells, Hunger.

A semi reasoning, look: Purgatory has a couple of motives to open it (a place which harbors/binds Leviathans), whereas Lucifer's cage (the only place that can trap Lucifer) is only accessible by the four Horsemen's rings conjoined.
