XY's animation is better than DP's, but I think DP has the better overall presentation in terms of story, and Dawn's side of things are stronger than Serena's. If you're into more low-stakes adventures focusing more on comedy (with some cool battles), SM maybe more up your aisle. You have to put up with Ash looking stupid, but once you get used to it, the art style is actually really good. AG is probably the best mixture of the two, especially once you get to the Hoenn League and Battle Frontier. May's Contests are better than Ash's Gyms, but the non-battle episodes are especially good. The Indigo League is genuinely great as well.
I can't really recommend Johto or Best Wishes, though they do have stuff going for them. Their valleys aren't worth the peaks that they get. Journeys is also okay, but the good parts of it require knowledge of past events.
