I cannot even install a Windows system with a local account anymore without having to open the terminal and enter some obscure commands.
A modern Debian or Fedora with KDE is a breeze otoh, I set that up for relatives and my SO, and they're all more than happy with it. Bugs exist, like in all software, but the friction is way less compared to wrangling with Windows nowadays.
Sure, if you're fine with double standards, every issue from Windows is a non-issue, even something simple as using a local account-or being forced to view ads even after paying (!) for the OS.
It's certainly subjective, but the amount of tech support I have to give has dropped significantly since switching the few people I care enough about to help from Windows to a mature Linux distro like Debian, while they are certainly not less productive.
