Ursala, Bonbon, Dobie, and Julia are probably my top favorites (not necessarily in that order, though Ursala is my #1 girl I adore her)
Except for Dobie, most of my favorites are rather uncommon/unpopular, lol. But I just think their designs are SO cute.
Ursala has such a sweet face, lovely hair, beautiful colors, and just looks like the epitome of what you'd imagine a sisterly villager to look like. Plus, she has a solid pun name, which I can always appreciate. I started playing Pocket Camp in the last month or so, and I FINALLY got her in that- she's now my camp caretaker, and I love it!
Bonbon also has nice colors, but her face is where she really shines. She just looks SO different than other villagers it feels like someone really poured their heart into her design. I mean, those eyes? That hair? Those cheeks? And, the best feature IMO, that precious crooked smile. Perfection.
I feel like I don't see a lot of people gushing over Dobie, but whenever people list favorite crankies, he tends to top A LOT of lists, it seems. And it makes sense why- he's just the perfect grumpy old man. He's the one cranky who, when he complains about aches and pains or getting lost, it's like "Yah, I can see it." Whereas ones like Wolfgang, as much as I love him... he looks like he could be a young model in the game world, lol. But I was really close with my grandparents and have a soft spot for the elderly as a result, and Dobie is just the perfect old man.
Julia doesn't get mentioned a lot from what I've seen, but she definitely seems to have some fans. And I just love her. She's SUCH an elegant snooty lady. Also, her expressiveness in ACNH is just lovely- I loved her when I first saw her, but when I saw her and talked to her in game? It totally sealed the deal. Also, I appreciate LGBT+ representation, and in my mind she's trans* Because she is CLEARLY male. ANd that makes me love her even more. Also, she was the star of one of my favorite avatars I've had on this site, for Halloween:
STILL love how that one turned out!
