I know this is separate from whom is older but I think in regards to how kill something you need to look at all the factors. Powers, the strength of those powers and things like strength, weaknesses and how many also restrictions like how both demons and angels to really interact with Earth need vessals. But also like how demons can take them without permission while angels need them. Stuff like that.
