I am so sad this has been your experience. From my first iBook G3 in 2004 to my last 2012 13" I have only ever had the most positive experience with the combination of hardware and software.
My wife has my old 2012 MacBook Retina for some hobby iOS development. Apparently all her friends are envious because it's the last Mac that doesn't suck. I don't know if it's true or not - but I replaced that one with a Dell because, as I always do when I buy a new machine, I consider my needs, the cost, and the benefits of the hardware, and for the first time in a decade Apple didn't come up on top. So maybe I agree with them too.
I switched from Linux to Mac about six years ago, because I believed it's better. Now I think that it wasn't worth it and I'm not even talking about money. It's overhyped. From the start, I was annoyed by various things (some things worked just better on my old Ubuntu), but recently I'm becoming fed up with it, mostly because of carbon, finder, lacking bash utils, touch bar, and crashes. I'll be switching back to Linux+Windows.
