Aww, I'm sorry if I made you undecided again. I just wanted to voice my side in case you didn't decode yet and then read the other posts, oops lol. Check them out in dream towns first though to make absolute sure you'll like them for your town, I know some people who originally liked villagers in pictures, but when they interested with them, the villagers didn't live up to their standards unfortunately. I have Elvis of course, so you can always dream of my town to kind of experience him first.
As for the second question. I suppose that would depend on which other villagers you have in town, and which personalities are repeating. From what I can see though, theyre both snooty so it won't matter that much. Also probably consider how they would fit with your town. I personally like Bree more, but some people seem to not like mouses as much. Plus she's named after French cheese lol I usually like to find little tidbits like that with villagers though.
