Well another reason most Pros chooses Apple is because of its Hardware quality. Not just paper Spec, but the actual quality of hardware, from power supply, USB plugs, keyboard, trackpad, Screen and many others.
Apple used to have many best in the Notebook segments. The problem is ( no idea why ) HP and Dell which dont used to compete on quality now has fairly decent Notebooks.
And since Apple has stepped back in a few areas, all of a sudden the price becomes a little hard to swallow. Arguably Windows has gotten better as well, while the macOS seems to be, having more and more unnecessary issues.
One way I dont buy the sales matrix argument, there are more people drawn into the Apple Mac ecosystem then ever, thanks to iPhone. Apple is now a luxury brand, and people will buy into the brand whether it is the best or good enough. And for certain older Apple users would remember:
It's a bar of excellence that merely good isn't good enough. It has to be great.
