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
Windows (~6 years) -> Mandriva (Mandrake? For I think 2-3 years) -> Ubuntu (1 day) -> Suse (2 days) -> Slackware (2-3 years) -> Gentoo unstable (2-3 years) -> Gentoo stable (2-3 years) -> Arch (9 years and counting)
The only span I’m sure about is the last one. When I started a job I decided I don’t have the time to compile the world anymore. But the values after Windows sum up to 21, should be 20, so it’s all more or less correct
