For me the thing that pushed me to reinstall windows after I got a cheap $10 copy was Kerbal Space Program. Though, in my specific case I strongly suspect it was older hardware & driver issues than anything else, since I've not had any major problems on steam deck.
I do have more random crashes on certain games even on steam deck, but not as bad as Kerbal Space Program on my old (12 yr) desktop.
Factorio seems to work better on Linux. Which is both good and bad (since it's so addictive).
Factorio can save without stopping the game on Linux, which it can't do on Windows, since they just fork the process and do it in the fork IIRC, which makes the saving something you basically don't think about on Linux, but bugs you when ever auto save runs on Windows last I checked
