Windows plays every PC game in existence and plays them better though. It also allows you to use the device as a pc replacement via displaying the screen on a tv/monitor. It’s the best OS to go with imo.

Windows plays every PC game in existence

There's a surprising amount of older PC games that don't work on Windows anymore, but work fine on Linux. I remember trying to play New Vegas a few years ago on Windows 10 and needing four separate mods just to get it to play properly, and even after all that it would still crash every 15-20 minutes. I've since played it all the way through on Fedora and SteamOS with zero tinkering and no crashes.

Not with windows you can’t, which is the OS the overwhelmingly large majority of people want to use.

There’s more that work and work better on Windows than Linux than there are the other way around though.
