I would personally say snooty because I don't really get too attached to them usually but I know some people who prefer to jocks. To normals are good too
Snooty When I get Freya in my town I will have 2 snooties. I also think normals are good to have more than one of. They are just so darn cute. I like to have at least 1 of every type of personality in my town
Jocks. I'm going to have double jocks once I get all of the villagers I want, and I might even end up getting a third one if I don't get double uchis instead.
I have double smugs and double lazies. However, I think that either double lazies, or uchis are the best. (If you're not a fan of uchis, maybe peppy or snooty.)
I think snooties are best for doubles. For it being just a game, snooties seem to either be really friendly with each other or really nitpicky with one another over who looks/wears something better, haha. It's pretty entertaining watching such a friendship have its ups and downs.
