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The hardware was really outdated at this point, so I got a new machine. Windows 8.1.
Got a different new computer with Windows 10. Started trying out lots of distros of VMs.
tldr: Windows Vista -> Mint -> Lubuntu -> Mint again -> Windows 8.1 (new computer) -> Windows 10 (new computer) -> OpenSUSE Leap -> Debian -> FreeBSD -> OpenSUSE Tumbleweed -> Debian again
