I bought two LG Ultrafine 5K displays in 2016 and they're still going strong. They're good — probably the best affordable retina monitor option available, but not perfect. For example, I wish I could daisy chain, and there are occasional ghosting when changing from a contrasty/bright screen to a dark screen. I also ran into problems this year with my MBP maxing out CPU when running both displays at once — after 5 years without problems. Switching to one display solves the issue.
If Apple released an affordable pro level display with reasonably good specs, I'd make the jump.
