I actually really like most of the normal villagers. In fact, it had gotten so far in my main town that I had Goldie, Alice, Vesta, and then Marina moved in >~< 4 normals was a bit much though, so I gave Goldie away because she's pretty popular.
Anyway, not a specific favourite, I just like all the normals ^_^
There's way too many Normal villagers I like. It's the personality which has the greatest number of designs I really adore.
I currently have Gala, and I think she's a sweetheart, though I'll admit that my liking of her is heavily influenced by... personal reasons, haha. Off the top of my head, I love Vesta, Nan, Maple, Goldie, and Lily as well.
I got Fauna in my town a couple days a go and I think she has earnt a spot a my favourite normal.
But Aurora and Peaches are my runners up. ~ where is their love. D:
Edit: Well I only read the first 4 pages, and now immediately see someone else votes Aurora. xP
But Peaches!!
Kitt, she was my best friend in wild world, and I am slowly trying to make that happen in New Leaf. Already got her in my town, just working on doing favors for her.
Nan is also all right. I didn't like her at first but she grew on me.
