Spell casters are the only ones I have really played, though I love the werewolf world, and I like the werewolf build buy and CAS as well. I do love the spell caster furniture, it really seems to fit them. I like some of the build buy for vampireds too, mostly the things that help a house look run down or abandoned.
I think that the spell casters are the most versatile of the 3. I can have them do full on Magic, doing potions and spells, or I can have them brewing up herbal stuff from OR, or I can have them doing paranormal stuff, or any amount of different combinations.
Having said this, I think they could have made spell casters a bit better to play. But, they are still my favorite. If it ever gets a refresh, one of the things I would like to see is them making the spell caster headquarters editable without cheats, all they need to do is make it where you have to have certain things there, and what amount of them. I would like to see some better spells as well, and a witches hat ( without a spider ) and a Dracula’s cape ( for vampires or witches ).
Also someone else mentioned being able to have a second form, that would be interesting too for some of my spell casters.
