Which villager should I keep

I’m definitely swapping Colton and dom (I hate him) out but currently contemplating on whether I should get rid of chrissy and cherry. I got cherry as my starter villager and I’ve never been a fan of her but after interacting with her she’s really sweet and would always give me medicine without fail whenever I’m stung by wasp lol.

I love Erik, Beau, fauna, poppy and Goldie but it’s so boring to have the same interactions as they’re all normal and lazy villager.

Would like some duck and cat in my island :c
