Does anybody really care that much about operating systems any more? The big three on the desktop - Windows, macOS, and Linux - are all good enough.
What matters (and I think this has always been true) are the applications. When friends ask for my opinion on what they should get, I almost always recommend buying from Apple (gamers probably want Windows). The two big reasons are (1) they can (legally) run more software than anything else and (2) you can walk into a store for support that's actually pretty good.
