The best gaming machine indeed runs Linux, and is called Steam Deck.
I don't like macOS, but I'd take it over Windows without much hesitation. MacOS is like an authoritarian but tidy country. Windows is more and more like a corrupt third-world country :(
I was thinking as a Mac user who quite likes Mac and also quite likes Singapore that that's quite an apt analogy. I gave up on Windows a while back. I guess Linux would be like the metaverse where you can be/do anything but not many people go there.
