Its all the same shit.
Same package manager, same debs, same systemd. The only real difference is that Debian doesn't have snaps. If you're not a retard about snaps, this can be a good/bad/whatever thing as snaps are more enterprise focused with up to date system level apps and not really great for desktop apps.
Since Debian's LTS comes out inbetween Ubuntu's LTS, it basically means you have one year newer packages, sans the kernel which is always less up to date then what Ubuntu offers.
