Honestly sitting here trying to pick is really hard. The only ones I don't really care for are jock and peppy. I'd probably make an exception for a really cute peppy villager, but the only one I was ever attached to was Carmen. I just never liked the jocks in general since I hate athletic stuff, but Bam stayed for a while and although I didn't want him to stay I asked him to move in bc I liked him enough so.
I don't know. My favorite personality would probably be normal, uchi, smug, or cranky. But then I also really love lazy villagers! And snooty villagers! So honestly I just can't pick and I thought this would be a lot easier until I looked at all of them again. Sheesh.
I might go with normal simply because they get along with almost everyone and I feel like I'd be a normal type villager.
