Well, my villagers.. quite a few are high tier. Not cause of popularity, but because of looks. I have the fabulous Julian because, I mean come on, he's a unicorn and I love unicorns. And then there's adorable Marshal, cute Marina, exotic Ankha, pretty Whitney, cheerful Chrissy... but then what about Fuchsia? I only took her because she was the most appealing to me of the uchi group and I'd already had Phoebe once. But she's grown on me and I like her a lot now.
And then there's grumpy Lobo who I decided to take over getting Fang again because I liked how he looked. I'm hoping to find Snake soon and oh my gosh can't wait to get sweet little Joey back in my town. He's so hard to find though because people tend to automatically void him.
Before I restarted my town I had villagers like Rod and Jay and Mint and I love all three of them. Heck I had Mint in the GC Animal Crossing and have liked her since. I may get her back if I ever decide to let Whitney go, but until then I will miss her. I also had Katt... she was.. interesting. I didn't like that I was stuck with her in my town at first cause I didn't like how she looked at all, but then she grew on me and I decided to keep her around longer before letting her go to make room for a dreamy.
Really it's all personal preference and you don't need to be embarrassed because you like the lower tier villagers. A lot of the cute villagers ARE lower tier.
Just look at cutie patootie Joey. How can he be so low in popularity. Love who you want and don't give them up just cause of tier or because others may think them ugly or something
EDIT;; why yes, I do realize how many times I mentioned looks. I suppose that was the wrong word choice. To make it short I like who I like and not for popularity reasons. I couldn't care less if they were popular or even if they were ugly so long as I liked them.
