For me, my favourite villager personality types would have to be smug, peppy, cranky and snooty.
Though the smug villager personality type is one of the newest villager personality types along with the uchi personality type, it's interesting to see how their lines portray their insecurities, their protective nature and their yearn for exploring/discovering new things. In my opinion, I find the smug villager personality type would be an ideal for everyone because a smug's personality attributes would do well in the real world. For instance, when Zell asked me to get him some fruit and I gave him a coconut, he took it pretty well. He didn't eat the coconut because he said that it could break his teeth but he also made a remark that demonstrated he was amused. Zell wants to be a film director as his profession, and I think that's pretty cool how he's developing himself to be prepared for his future.
I used to not like the peppy villager personality type because they have a high-energy vibe which would actually wear me down if I hung out too long for my liking, but I had a changed opinion when I engaged in interactions with Twiggy. She sounded like the type who cares about her friends even though she's aiming for stardom and celebrity status. Personally, she reminds me a bit of myself.
The reason why I like the cranky villager personality type is because deep down they're emotions can be compared to a concerned parent for their child. There is actual genuine concern with good intentions even if their lines are brash and sounds insensitive.
When I first played the original Animal Crossing for the GameCube, Olivia rubbed me the wrong way? But as I continued to follow the Animal Crossing franchise and play the games, I've found the snooty villager personality type is meant to represent that we all need a tough exterior to protect ourselves and our individuality from others who disapprove without good reason. I have found that snooty villagers act like princesses, but I'm just so happy that snooty villagers like Kitty wants to be a CEO and Opal wants to be a doctor, rather than a profession like fashion model.
