Mine is a tie between Poe & BB8. BB8 is fun in almost every scene it's in (unless just rolling along). Poe? I liked his intro. And then he wasn't really in the rest of the movie.
I agree that BB8 was great, and that's who I actually voted for in the poll. BB8 was funny, especially the lighter as thumbs-up thing with Finn. It emoted very well for what was basically a soccer ball with a hat that speaks like R2.
