In Sims 3 witches were my favourite occult but in this game I think vampires are the better thought out and developed occult. Spellcasters are fun and work well when playing a sim who just uses practical magic to make freelancing from home easier but most of the spells just feel like cheats and aren't as interesting as Sims 3 Supernatural ones. Comparing packs from a build point of view I get far more use out of Vampires than Realm of Magic. End of the day I like both, don't have werewolves so can't comment on that pack.
