For me it was:
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).
Also, when trying to switch from Gentoo to Debian, I fucked up all my data with no backup.
What was your journey?
EDIT: Added Windows
Apple IIc > Windows 3.1 > Windows 95 > Windows 98 > Windows XP > Brief experiment with Ubuntu in the REALLY purple and brown era > OS X > Elementary > Fedora > Endeavour > Fedora > Silverblue > ublue > NixOS
(not counting numerous VMs with everything from Debian to Linux From Scratch)
