I didn't vote because I only own Vampires of the three, so I can't really compare. I actually bought Vampires for the build and CAS, so that I could have stuff for my goth humans. Wasn't interested in the Vampire game play. I had played with vampires in Sims 2 just once and was bored to tears. Not to mention I'm no fan of immortality. Had my fill of that with the original Sims game.
Then, I had a character fall in love with Caleb Vatore. When he moved in, I was originally planning to de-vamp him, but I started playing with him as a vampire and came to an astonishing discovery. Vampires in the Sims 4 are actually really fun! They are so well thought out and their strengths and weaknesses strongly impact the game play and make it more interesting. The fact that they can choose different paths allows them to be individuals.
When Realm of Magic was announced, I was intrigued, but then I saw some let's plays and decided they were pretty underwhelming.
