Windows (for many years) -> Ubuntu (for a year) -> Arch Linux (for half a year) -> Void Linux (literally 2 days) -> Artix Linux with runit (a month) -> Gentoo Linux (another month) -> Debian (finally, I don't plan on changing it).
Windows 95 - Windows Vista - Windows 7 - Ubuntu - Fedora - back to Ubuntu
Think that's it, can't recall the years exactly
The switch to Ubuntu was like in 2014 or something
