User blog comment:EmpyreanSmoke/Leviathan VS Archangel/@comment-188.4.147.206-20140826134718

Leviathan's main advantage is their almost indestructible while you can kill an Archangel with a blade. However Archangels have a lot of abilities such as Holy light or cause earthquakes and lightning storms. Plus Leviathans seem not to have supernatural perception since Dick couldn't see Bobby (a ghost at that time) and Bobby was able to push him back several feet by force.
