I ran a mix of Xubuntu and Linux Mint full time for a few years but switched back to Windows just a few weeks before Valve started releasing the crazy updates to proton in the lead up to the Steam Deck launch. I have one laptop which still has the same Linux Mint install that I did a few years ago too! But I ultimately switched back because a couple of games I enjoy were either a royal pain on Linux or did not work at all, plus I'd tinkered with my installs to death so they all had some wild issues that I never could pin down.

Decided with the Windows 10 EOL date that I'd try out Bazzite and see if I liked it, and honestly I expected to have found a blocker by now but everything I keep trying keeps working flawlessly, and I even got a couple of 25 year old games that don't even work on Windows working flawlessly on Linux with just a couple of toggle switches in Proton
