Hmm personally I like queenie’s house better so I’d choose queenie. Do you want to have all personalities on your islands? If so, you might also want to think about it in terms of the other snooty and uchi villagers in the pool. Personally it’s more difficult for me to pick snooty villagers than uchi villagers because there aren’t many snooties that I like. For that reason, if choosing between two villagers that I equally like, I’d go with snooty than uchi, because Its easier for me to find another uchi than snooty.
Honestly, I do like Phoebe a bit more than Queenie, mainly because of her design and her house. However, I would say definitely keep the villager you like the most. If you like Queenie, then keep her. It's not worth it to stick with a villager only because of popularity, after all you should like the villagers and it doesn't matter at this point what others may think.
