sorry? obataining the blood of a purgatory native is easy? regular monsters won't do. the only solution is to release a creature that was either born in purgatory or died and went there from purgatory ( which requires a door). And it didn't take decades to open lucifers cage it took about a year as lilith broke the seals pretty rapidly and the boys actually obtained the rings in less than that. plus crowley and cas combined could probably get them as crowley got death's scythe with little difficulty, pestilence can't harm cas when hes fully charged, and the others don't have powers that could work on cas really. also leviathans can have cars dropped on them and walk away, if an archangels power doesn't work on them ( which seems likely) than they could easily eat them or poison them with black goo. conclusion, though it can't be proved leviathan beats angel ( even archangels) though i recon it would be close
