S Tier
Ankha is my absolute favorite of the Cat villagers; her Ancient Egyptian pharaoh design is so cool, especially with the little cobra. I had her in my main, horror-themed New Leaf town for numerous years until deciding to move her out and send her up into New Horizons since she fit my island's theme of a melting pot of different cultures and time periods. She's one of my favorite Animal Crossing villagers in general; not
the favorite, but definitely in my personal top tier.
Bow and Meow are really neat with their digital screen faces and, while I know they were linked to a long since defunct real world technology, I wish they could come back anyway. The concept is SO GOOD.
I personally like clown aesthetics and am fond of clown villagers, so I really like Pierre. I wish he would come back to the series eventually.
A Tier
All fantastic villagers.
Raymond is really cool with his office suit, the heterochromatic eyes, the bluish-gray fur coloration and the tuft of blond hair.
Always been fond of Kabuki's design and had him as a resident in New Horizons for a while.
I like villagers with unique aspects and/or accessories, so I like Kid Cat and his superhero design that pairs with Agent S, Big Top and Rocket.
Not a whole lot to say about Kitty and Olivia, I just like their designs a lot.
Finally, I love Monique's design that's clearly inspired by Marilyn Monroe.
B Tier
All solid designs that I like but that are just below the threshold of the A Tier level. Felicity might be A Tier depending on the day. Kiki's nose could stand to be a few sizes smaller but otherwise good and I like the reference. Mitzi would probably be C Tier if not for the fact that I had her as a resident of my GameCube town.
C Tier
They're fine but I don't have much to say about them. Tabby and Katt are fun with their intentionally "ugly" designs but I don't like them as much as those in the B Tier, so threw them here with the others.
D Tier
Same as the C Tier, they're fine but I just like them less than the C Tiers. Not much to say here.
F Tier
While I like Lolly's gray coloration wit the black accent lines, I greatly dislike her eyes and she's one of those villagers whose lack of a nose really bothers me (it's a subjective pet peeve). Merry, meanwhile, is like an inferior Felicity but with a bad haircut.
