I always assumed the software is newer. You can update to a LTS more often, if your server needs that. For example, I think podman adoption is hampered by Debian's slow release cycle. Trixie finally supports quadlets.

Debian often ends up as Frankendebian, or with custom repos added. How do you run e.g. Nextcloud on Debian? Where do you get the new php version required for the upgrade from? Right, there is a community repo somewhere...

I should mention this is maybe not an issue for servers with containers, nowadays. And desktops have marketplaces and linuxbrew.

But it took 3 years from Debian 3.0 to 3.1, then 'testing' was frozen for 2 years. A lot of users were lost to Ubuntu at that time, which released every 6 month.
