leviathans are probably stronger than archangels but don't have their range of abilities. they are immune to an angels power ( probably because like eve they know what makes angels tick) and their black goo appears to be toxic to the angels so if both these factors are the same for archangels : leviathan ( at least high ranking ones) beats archangel. this would also explain why god locked them in purgatory and didn't ask michael to destroy them once he was created. because he thought there was a risk that michael would be chomped. also death states that leviathans would chomp the whole pietry dish which would include ALL humans, angels, ect. safe to say they are superior to most creatures except death, god and i expect jesse as castiel states jesse could destroy the host of heaven with a word, and that would mean killing thousands of angels which would be at the same level as godstiel as he too killed thousands of angels in mere mins.
