I liked Chestnaught's design, it caught everyone off guard. Who would have ever thought the cute little Chipmunk would turn into this brute?
Delphox was odd but likeable. Greninja is my fav (Even without Protean) especially since I was team Froakie.
I also liked how the few species they introduced in Kalos didn't necessarily suck. Honedge can be bred to be this mass murderer. Tyrunt has a decent egg-move pool, larger than most Kalosians. (Which is the only qualm I have with Gen 6, all of the new species have a small egg-movepool, even tinier than Gen 5's species when they were first released. I don't get why, and I hope they'll fix this with the next entry in Gen 6.)
