There really isn't one.
On Linux you have to download countless of "updates" every day, you can't check all changes, even if you were a developer, so in the end what's the difference.
And your computer has its own "OS" on top of that anyway.
I'm staying on Windows 7, but with an up-to-date and ad-blocking and telemetry-blocking browser.
That way I can also keep on playing Tomb Raider 2.
