What operating system do you use on your main computer?

I’ve used Debian Linux as my primary home desktop since 2005 and at work since 2008. I’ve never had a job that required a Windows machine and at this point it’s a deal breaker for me.

I specifically use Debian stable. In my first decade of using Linux I wanted the bleeding edge, cool stuff, but for me nothing interesting has happened to my machine since 2015.
