There are plenty of uchis that I like and they have some of my favorite dialogue in NH even, but I still agree with you on this and it's part of why I'm baffled that there are only 8 new villagers in this game. When I found out that the 8 villagers we had seen revealed before release were the only new ones I was honestly really disappointed and I think that at the very least they should've added a few more smugs and uchis to compensate for the fact that they were just introduced in NL

I hope we'll get more new villagers through updates or something but I'm not really expecting it.
Edit: If it helps at all, these are the uchis that I like--Phoebe (one of my fave villagers overall!), Plucky, Agnes, Diva (I know lol but she moved into my NL town at random once and grew on me), Flo, Frita, Muffy (wish the sheep didn't wear shirts in this game though

), Ursala, Shari, Mira (another one of my overall faves! I just wish her house wasn't so weird compared to NL), Reneigh, Pashmina, Katt, and Fuchsia! So yeah, I think that's actually the majority of them! A lot of people also like Cherry and Deirdre and I'm not really too into their designs but they're still cute. Hazel is also okay but I don't like her color scheme, and I know a lot of people dislike her unibrow.
