Ankha is my queen, so yes, she's my favorite snooty villager. My favorite uchi villager might have to be Hazel... Only because I appreciate her fuzzy forehead caterpillar, AKA her unibrow.
My favorite snooty is definitely Whitney. I love wolves and we share a name, so I've always had a connection with her. I had her for years in City Folk and she never said anything rude to me. She was busy classy, dignified and stylish. I chose not to have her in my town in New Leaf so I could experience someone new this time around. In New Leaf I have had Vivian, whom I also love. I'm curious about Yuka and Blaire though, and I'm thinking about trying them out soon.
As for uchi, it's a personality that I actually love . The fact that they aren't as popular makes me love them even more. My favorite is Muffy followed by Pashmina, I think they're both lovely.
My favorite Snooty would probably have to be Ankha. I really liked her design as soon as I saw it in my original New Leaf town and, when I restarted it years back to create my current main town, I went out of my way to get a town with her and Lucky as starting villagers. A bit of a poor choice in retrospect because her house is out of the way from everyone else's and the map of the town isn't the best, but I'm still quite glad that she's a resident of the town. Her design is really striking, she goes well with Lucky, her house's interior design is great, and I've gotten a throne from her before. All around a great villager.
Other absolute favorite Snooty villagers would be Freya, Julia, Pecan, and Tiffany. There are other good Snooty villagers, but these all would be the best as far as I'm concerned.

My favorite Uchi would probably have to be Phoebe. I'm fond of birds in real life and I'm fond of more unique villager designs in Animal Crossing, so her phoenix-inspired design is great for me. She's a resident of my all-bird species town as one of the Ostrich representatives and she's great.
Other good Uchis for me are Agnes, Deirdre, Pashmina, and Rocket. I also like Muffy's design, but I've had her in a few towns and have let her go each time to get a different villager instead.
my favorite uchi is probably tied between diva, fuchsia, and muffy and my favorite snooty is francine! i'm honestly surprised diva is considered one of the uglier villagers, i really like her design!
