Katt she's just so spunky and fits the uchi personality really well. Her house also in my opinion, defines the uchi personality pretty well and it helps me to imagine what she'd be like if she was real. She just has that tomboyish uchi look to her, which you cant help but like her for, although a lot of people consider her to be ugly, once you get to know her that's definitely not the case!
Also Mira, although she's pretty popular on here she is very charming. Mainly because of the fact she's based on Sailor Venus and if you're a sailor moon fan like me you'd understand why I like her so much. That aside she does have a pretty funny facial expression when she's surprised and a good colour scheme.
Mira is my favorite Uchi, and I also really like Fuchsia. But Muffy is also up there, she's one of my favorite sheep villagers.
In AC:HHD I made her little house very gothic looking and it ended up being so adorable!
Canberra is actually cool! You can go for her. But Shari has the better-looking house. Furnitures change from time to time anyway and Canberra's house may not be as good as Shari's but it's not that shabby.
Or you can go for Phoebe or Renee. I like them both.
Fuchsia is a really rad villager. Her apperance and house are both really cool and she's just so spunky! I mean who doesnt want a puck-hippie deer in their town??? I've had her for quite awhile and i have come to really enjoy her. I originally had Pheobe (who I now have in my 2nd town), but during a TT accident, I lost her. I replaced her with Deirdre, but it didnt feel right, so I soon traded her out for Fuchsia and can definitely say she's now my favorite uchi villager due (even over Phoebe) to her awesome appearance. She also suits my town well
