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
The “+” indicates a dualboot
MacOS (for a while) → MacOS + Windows (for a year) → Ubuntu + Windows (for a year) → Linux Mint + Windows (for 6 months)→ Linux Mint (for 1.5 years)→ SteamOS (for 9 months) → SteamOS + openSUSE Tumbleweed (for 3 months, then tumbleweed got glitchy with display output) → SteamOS (Current) → Fedora Linux (when I get my new laptop)
