It depends a lot. If you are never using MSOffice for anything other than the most basic writing Libreoffice does cut it. Linux overall does just work for the most part if the person using it just plans on using the browser anyway. Everything else is spot on tho.
And funny thing about the gaming performance bit, I’m no expert and this is anecdotal, but my games actually run better on Linux than Windows by default. Dunno why
Tbf, that’s just in regards to the current tests. It could change later on.
