I have a Pro Display XDR and I'm somewhat happy with it. I had a Cinema Display before, but after a while, I found it too small and all my open windows were just too crumbled. That's really the only reason I upgraded to the Pro Display.
Of course, image quality matters to me. I'm not a professional who works with image though, so I can't judge that part.
What I do wish or what annoys me is that…
1) There's no built-in camera. It's not particularly good quality, it's one additional cable you need, it takes on additional port on your display, and it also means additional effort when vacuum cleaning. It also looks less minimalistic on the back or more ugly in general, sitting at the top of the display.
2) There's no built-in microphone. I use dictate a lot (for example to type this here). And FaceTime/calls. The Logitech camera has it built in microphone, but it's not particularly good. Much worse than on the Studio Display.
3) It doesn't have any speakers. So you need extra speakers. That takes extra place. And it needs extra effort to clean it from dust, etc. I wish it had speakers of the quality of the Studio Display. They were really fantastic.
As for the Apple Chip… I'm not sure what exactly the purpose of that is? I know the Studio Display has one. What is it meant for?
