Sun/Moon are better, hands down. I was worried about that fact that they removed the typical Gyms but the Trials are so much more fun.
Now that I've finished the story, I have only 1 complaint: It was easy. They randomly heal your pokemon too many times. I would've added on the challenge level when you actually have to struggle to keep your pokemon healthy. Now, every time you're going to face off a trial totem or some kind of boss, they heal your pokemon =/
Yea, that sucks.. This marketing scheme is annoying..
