Can you tell us what you thought about each of the previous generations?
1: Pretty bad but who can complain?
2. Loved it! Such a big improvement!
4: Good. Only played Pearl, though.
5: My favorite! Great story, and the sequels are my favorite main series game.
6: Like them! X and Y had so much charm and I thought ORAS were great remakes!
7: This is where things start to peter out with me. I thought Sun and Moon were just okay at best, and then I absolutely hated Ultra Sun and Ultra Moon for being the exact same game. I forgot to mention this in the OP, but USUM were part of the reason I had a bad taste for Pokemon, and the abandonment of the the third version makes that better.
Edit: Also Colosseum and XD: Gale of Darkness are the unquestionably best games in the series.
