Despite hardly posting or commenting, Instagram is the only place I've seen relevant and interesting ads. Like scary good advertising. My wife has had the same experience, she was blown away that the ads are actually relevant where everywhere else, including Facebook which has the same or more info, acts as dumb as you can possibly be. I've heard others say the same. I don't know why they are so much better at ads or literally everyone else sucks so hard that just doing as would be expected appears exceptional. The addendum to this is that in the last few months this fell apart for her account and now it's turned irrelevant.
