@retrovulcano I'm sure you already know, but others may not, that Ubuntu is itself a Debian-based distro.
Despite the claimed "usability" advantage, Ubuntu is produced by a commercial organisation and therefore tends to push it's own agendas on the user. In the past, that has involved selling desktop search queries to 3rd parties. Now they are trying to get traction with their semi-proprietary snap store. Debian, on the other hand, is scrupulously free and open, and eschews proprietary tie-ins.
