Although Francine would fit way better in my town, and I like her more, I'd have to go with both! It just seems like it wouldn't be right if only one was in a town, and not both.
I think Francine, but if I had a choice to choose both then that'll be the answer! They look like a good set pair in animal crossing, it would sometime seem lonely without the other pair, but each on their own is good too cx
Both because splitting them up seems too sad. If I had to pick one, I'd pick Chrissy because I like pink and peppy villagers. However, I think Francine has a cuter face.
