I've met a huge amount of duals, if my type is right. They're pretty much all over the board, though I never had a negative experience with any of them. Some of them have had subtype/enneagram/individual quirks that made me think they were IEEs even, though I can say I'm at an age where I'm still developing my tertiary function as are my peers so that may explain the confusion. I grew up with my brother who's my dual, raised under a dual beta couple. That was fairly interesting growing up.. I suppose I'm pretty lucky though

I have met 3 duals who I'm very very fond of, and then others I almost instinctively dismiss. Really hit or miss, the ones that are obviously very mal-adapted in general I obviously avoid for reasons of saving my own time and effort. Maybe I shouldn't though
