Favourite premade households to play with

I almost never touch premades; they work as recognizable background characters, and I'm always afraid of "ruining" them. Whenever I use them, I try to try to do what I think the devs would have wanted for them.

I'm trying to turn that around with Vlad. He's a mentor to my main family's vampire branch, but he wants to control them due to plot-related reasons. I really like the character, so I want to focus on playing him, instead of making him a side character. He's going to adopt a magical child for somewhat nefarious purposes. I feel like he'd be a great (if evil) parental figure, so it'll be fun exploring that.
