I actually thought spellcasters were the most popular, but perhaps not? I love occults, including spellcasters, but I must admit they are not my favourite. Realm of Magic was such a disappointment for me because I was hoping for something more like Makin' Magic. I particularly wanted a magic skill or at least an alchemy skill so other occults could make use of it (I am still hoping for hybrids for this reason) and I wish child and toddler sims had some magical abilities.
I also think vampires (and possibly werewolves too, but I haven't played them yet) have more depth than spellcasters. Their powers and weaknesses and optional dark form gives them more versatility and personality. Being a vampire is a big part of their identity, for better or worse. They can be the most powerful sim ever or more challenging to play if you prefer. There are some things I would like to change or add about them, but they are not far from perfect. I have always loved vampires though so I am biased.
