I think my pipeline was like Ubuntu > Kubuntu > Linux Mint > ElementaryOS (briefly) > Manjaro > Arch
I never pushed past into the Gentoo rabbit hole but i think settling on Arch has been the best move for my own setup.
Still tempted to try out Nix in the near future, the reproducibility of it just seems so nice to have as I usually forget to document changes I make and have to relearn some stuff when I do a clean Arch install somewhere.
