Most enjoyable occult for you?

Hands down, vampires. I think 4's vampires are the best vampires in the entire Sims series. I don't dislike the others, but they are all lacking in flavor otherwise. Spellcasters in particular disappointed me because witches in every other iteration were my favorite. Beyond the spells and potions (which have very similar effects to a number of other things already in the game), all they have for flavor is an empty magic realm and affectless cosmetic swag.

It felt like the magic realm ate all the budget for magic equipment/items/progression and integration with other packs (like occult essence potions from 3, for just one example). Also, it was completely bugged at launch and to this day, the exp cheat is bugged.
