By that logic, that makes meg stronger than eve, azazel, alastair and lilith as she's survived six, possibly seven seasons and crowley's survived three. Their survival rate doesn't prove power just luck. As others have stated, no one can really prove it and Leviathans have proved to be stronger than angels and most likely seraphs. Archangels could possibly be stronger than leviathans but if their powers have no effect on the leviathans then they really don't have any defense. But we'll most likely never know as the only two archangels are imprisoned and the others are dead. And who knows maybe in the finale Dick will demonstate some new power or maybe he'll just be the same and die, either way nothing can be proven.
