I like Francine and Kitty. Kitty was one of my starters, and we had the biggest relationship until I fell for Sterling xD But she was still one of my favourites.
Diana. I didn't like her that much when she randomly moved in. Now I regret giving her away.
I also really like Ankha. Her house is in the same 'row' as Lucky's. It's kinda cute haha.
I don't care too much for Monique but she was probably the villager that never left my town in WW. It's nice to see some dedication while everyone was NOPEing their way out.
Tipper. I'm not sure why, but when I first saw her (in Nintendo's dream town?) I just liked her instantly. Part of the appeal is her colourful rainbow tank, horns and hooves, and for whatever reason a black-and-white cow feels kind of familiar and 'classic' in a way to me. I was surprised to learn she actually had a snooty personality and would love to have her in my town someday.
I also like Francine and Monique's designs (still surprised that Monique isn't as popular as I thought she'd be), and a few other snooties.
My favourite snooty is definitely Freya. I love the wolf villagers and I also love pink, so it's a perfect combination. I'm campsite resetting for her right now actually.
