Nowadays OS matters pretty little. Personally, on some level, I don't even notice difference working macOS, Linux and Windows. Other than platform specific development work, it doesn't really matter in the big picture. Other than that, only Linux allows me true visibility to its innards. Fast to fix almost any issues, should they happen. And I say this as someone who has for example no problem debugging Windows kerne…
I think 90-99% of users only use Browser+Office+Games which could work well in any of the big operating systems. Some software preferences are superficial and appropriate replacements exist on the other platforms.
As someone working with macOS, Linux and Windows I focus my workflow on the things that work under all of these operating systems so the impact they have on me is very little. People who are deeper into the UX of a single operation system may disagree completely.
