Re eccentric bottom brackets, I don't think you can just say "They don't work". There’s a few different ways to do them and, ime, grub screw v bushnell is like comparing apples to aardvarks. Admittedly I've no idea how the ones that go in press fit shells compare to a ’proper’ one having never used one but my experience of using a bushnell on a bike with a coaster brake (so gets pressure on the cranks in both directions) leads me to believe it's totally possibly to have one that doesn't creak or need constant adjustment.
I think they do need a bit of skill/care/understanding to set up right so they maybe suffer like GXP bbs do with the “its not me, it’s a shit component” kind of attitude.
Agreed, it’s like everything, there are good ones and less great ones. User error is very common from my experiences too, they are not the normal option and that throws a lot of people
