My progression was: Mandrake, OpenSUSE, Ubuntu, Gentoo, Arch, NixOS. At work I use Nix flakes on Debian machines, so one month back I figured out I could install NixOS at home to get familiar with Nix. NixOS is really something different and it brings me back to the old times when Linux was new for me. It’s again an adventure!
It does not matter what you say in a date. Only figure of merit is if you get laid afterwards or not.
