I chose Amiibo, since I know who I want the majority of my villagers to be... but I am taking my time with it, and want to scan them in every few weeks (though I am still waiting for some of the cards), while holding open a spot for one random move-in eventually. That way, I can still experience other villagers through island hopping and the campsite (not doing any of them very hardcore though, since I don't want to spend hours and hours on it). O, and the campsite method I am not doing at all. Way too much time spending TT'ing instead of playing the game.
I have traded, but with the exception of one or two trades, it took ages (some couldn't get the villagers I want out on time, etc.) and I got scammed once. I did have pleasant experiences and am really grateful for those people, but I am never going to buy a villager again. I am planning on giving the ones that are moving out away, since I think it is sad to void them. But I am not holding spots for several days again (which was partly my own fault), while not getting enough sleep because of waiting. And trading often included TT'ing - which was fine for a few times but I am not making it a habit.
So yeah, I mix of everything excluding trading and the campsite method at the moment it is, then
