It may be a bit of an oddball Pokemon to consider, but I personally think that Sliggoo is pretty cute. I didn't at first, but once, as I was trying to evolve it into a Goodra, I decided to try out Pokemon amie and immediately fell in love with Sliggoo and her antennae, devolved eyes, and goofy smile.
I'd have to say that the Pokemon on my list would be 1. Vulpix, 2. Eevee, 3. Dratini, 4. Minccino, 5. Aron, 6. Fennekin, 7. Rattata, 8. Mudkip, 9. Fineon, and 10. Sliggoo,
