Mint - it was my first one, and the one I come back to, having tried Manjaro (ooops), Endeavour, Fedora, MX, Garuda, Nobaro and probably a f ew more.
Yes packages are not bleeding edge, but flatpaks are good for me if I want newer versions.
I don't want to spend time restoring backups in the event of an Arch based release going wrong (happened to me on Manj and Endeavour - yes it can be recovered but its a waste of time).
