I use Linux Mint at home and Windows 10 and 11 at work. The UI is basically interchangeable, I use both in the same manner.

I’ve had zero reliability issues and Mint was easier to install than Windows when I did it 4 years ago (not had to reinstall it yet, just kept on updating).

Games wise, I just play stuff through steam or classic emulators and it works well enough that typing this is the most I’ve thought about how it works for a long time.

I’m guessing the people who complain are running some gnarly full-custom linux on new hardware and trying to get the latest games to run … that was once me, I now use a PlayStation for newer games because PC gaming was just a bottomless money and time pit.
