Debian, is definitly good to substitute Ubuntu. Although as mentioned flatpak/appimg is a must. Example: waterfox installed from outside repo made for Debian bookworm complains about dependecy issue, Ubuntu drivers just works Debian had a discussion about non free drivers in standard repo. Repo is named non-free-firmware, and still broadcom is not in standard repo you need to add repo. In the end you’ll have low maintenance distro, setup is more engaging for some hardware.
