Tbh, I would say pick an Uchi who helps contrast the color of your villagers. For instance, pick an uchi/snooty that is a different color than all the rest of your villagers.
I actually had taken Skye since some one was giving her away 100% original which was also pretty cool. If they weren't I would've picked Phoebe. Now I have a town with the most monotone villagers, except Rosie.
