Linux is very easy to install and use these days, it's still kind of finicky though so expect to use the console if you want to do more than the basics.

I've been using Linux on and off for ten years now, including a few stretches where it was my only OS for years at a time. I actually prefer it to Windows overall but at the moment I'm on Win10 because I missed too many games. If I was a console gamer I'd probably still be using it, honestly.

For maximum support and ease of use I'd recommend Ubuntu or an Ubuntu based distro (Linux Mint is currently super popular).
