Started with Slackware 1, then RedHat 4 (non-el) and when that needed a re-install on a major upgrade, switched to Debian. (In '95-'96). Only re-installs I did since then were after failing hardware or on new systems. (Tried Ubuntu once, that system runs Debian now ;) )
Rolling upgrades are great, but leave a mess, which is why I do a clean install on new systems. (Unless the laptop dies and the storage still works, then that is transplanted with the idea of just copying data and ends up main disk until the setup dies)
