To be honest, the only sixth gen starter I don't like as much as the others is Froakie, but then it's just by a small margin. I think both Chespin and Fennekin are excellent starters for a change, and I'm usually not someone who really hates any of the starters from any gen either.
Amen to that! Sorry for the delayed response. My cell phone's service has been suspended until my family can pay off our bill, so the library is my only Internet source (at least for the time being).
