It's funny, but I had my grandmother on Linux for about a long while before she passed... Wine managed to run the 3 Windows 9x era games games she was still playing into the 2010's (where real Windows wouldn't) and her browser/email. I wasn't even able to do that for myself. All I had to do was run updates for her every few months (because she didn't) and the one time she had a hardware failure, I'm the one who fixed it.

In the end, I'd say for most people, who aren't their own computer admins/repair anyway... Linux is probably fine. Since most people don't use more than the browser for the most part.

My other grandmother was on a docked Chromebook after the 5th time I had to clean malware off her computer, and she didn't need any windows apps anymore... she couldn't help but click on the "you might have a virus" ads.
