I have played both a lot. I think I have played New Leaf more though as I have played it more consistently over the years, and I do still sometimes load up my file even though I essentially consider my town finished now. On the other hand, I played ACNH a bunch in 2020 and then stopped after however many months before resuming this year with a fresh island. I have been playing it a ton since making a new start. Sometimes a reset is just what a person needs to be inspired again, although I would never restart my New Leaf town since I think it is perfect and I love the layout and my villagers.
Both games have good aspects. I hope to see a new title come out sometime in the next few years that takes some of the best elements of both games and combines it with some fresh features. I'd like the return of mini games and main street in particular while keeping the extensive outdoor decorating in New Horizons. That's just what I hope to see. I'm not sure what new story or direction they will go, but it will be exciting to find out.
