I'm not a fan of Uchi either. On the plus side, I will say they seem to be the personality type most likely to be overjoyed by a goods exchange that they'll leave the transaction skipping and singing. I love that about them. Shari was my first Uchi. I liked her, but there were several things about her that bothered me (she treated me like a pest if I spoke to her more than three or four times a day--"this guy again," and she was almost always in the museum when she wasn't home. I'd rarely see her interacting with the other villagers. Still, I miss her since she left and I like her more than some of the other Uchi villagers I've met. Fuchsia is in my town--I'm not a big fan. I have a second town with Frita. I haven't interacted much with her, but I think she's pretty fab.
Honestly, like I said before, Nintendo's just trying to teach us a lesson. So far, IMO, Phoebe's the only character where the rule doesn't really matter. She's pretty and she's really sweet!
I think Shari and Agnes are adorable, Fuchsia, Cherry and Phoebe are ok. I do wish there was more choice though, and there are a lot of weird/ugly uchi villagers. I actually think the jock villagers have a worse selection, however.
I don't think the uchi villagers are that bad. Paula moved into my town today and she seems quite nice. She has a fairly normal bear color that topped off with a hippy fashion style. I think she'll make a nice addition to my town. Also, she will be a great help for when I keep getting stung!
I'm really happy with Fuchsia, personally! :3 I think she's super great. I was thinking I wanted Agnes more, but then Fuchsia dropped a perfect plot in my town and I totally fell for her! I also really adore Hazel, Frita, Mira, and Muffy; but that's me! I have a real soft spot for the strange and high fashion types. I think the whole personality type has a lot to offer in form of diversity. really; I find a lot of people seem to prefer the really plain, cute villagers, which is perfectly fine and you know, do what you want with your town! O: But I think the uchis offer a lot of sassy cuteness, so I hope that everyone comes to appreciate a little bit of a different look through that personality type (assuming everyone gets 1 of each, which I find pretty essential to keeping up a variety of personalities).
Eep. I have Katt. She is rather ugly, but... She is the nicest villager I have! She sends me the most letters of anyone, talks to me the most, ect. So yes, it's more about the inside than the outside for uchi villagers~
