I don't think that there is a comparison of any kind. In BtVS, the vampire is a non-corporeal parasite that takes over the host's body after the host dies. In Sunset's case, the Element of Magic seemingly exposed her true nature - the quality of her soul - brining it to the surface. She had turned herself into a monster by her amoral and openly malign actions. All the Element of Magic was make her a monster in body as well as mind.

From how she acted after the Elements had depowered her, I gather that it was something she didn't want to be.
