Personally, I've been Linux user for quite sometimes, only using Windows when I really need it. I've been on Kubuntu and and don't see myself changing, I love the KDE interface plus it's really easy to use.
I just made the jump to Linux Mint last year from Windows 10, since the latter's EoS gave me a good excuse to finally stop putting the change off. Loving it so far!
Still Windows, though I should probably move this PC to Linux. Sadly, video game modders aren't great at making their tech work on other operating systems.
