There’s the Linux Mint main distro build off Ubuntu and a separate Linux Mint Debian distro build directly from Deb.
Specificity is useful, especially in the context that you said “Mint is built on Debian so it’s stable as fuck” - well actually, not directly. It’s built on Ubuntu, which a lot of people complain has a more bloat and thus less stability than Debian.
Personally I’ve not had issues with any of the three, they’re all good, but there are differences. Mint includes a number of packages that Debian does not (PPAs, Snap, Wayland infegration), because it’s inherited them all from Ubuntu. Mint is 64-bit whereas Debian supports 32/64 and other architectures, because again… Mint (standard) is based on Ubuntu, which is 64-bit only.






I think they’re referring to the name of the company being very similar to “immutable”, no?
