Firstly, don't go out of your way to try and convince or force people, but TL;DR – if you have an opportunity and want to give someone a solid start, my recommendation is always Linux Mint.

My mother asked me to switch her in September 2022. Some bad Windows Defender definitions update started triggering warnings every 5 minutes starting at 2AM or something riduculous. I got a frantic call to come over because of "someone hacking her computer" fully expecting to just fix whatever was busted and move on with my day.

After a conversation, I installed LMDE for her and set up automatic updates plus Timeshift. She has had exactly two problems since then:

• she forgets that the scanner isn't accessed by right-clicking the printer's tray icon and messing with settings

• she didn't like that she can't move desktop icons to wherever she wants

She was also just about the easiest switch there could have been. Like many older folks, her primary use for her desktop is web/email and she has already been using Firefox/Thunderbird since the '00s.
