I've done this multiple times when new Debian Stable was released (Bookworm just got released). Its great, until it isn't (ie. you need more up-to-date software). Although to be fair, you might be comparing Ubuntu LTS with Debian releases and the minor Ubuntu releases get short support. Ubuntu is akin to a polished Debian Testing snapshot. I don't like them swapping to Snap either (snappy it ain't).
