TLDR: No consistent use case

Premise: open source Is good also because permits forking the code, but is not all gold.

A lot of derivated-distros was made out of the main 4 (Debian, Slackware, Red Hat, Arch) some with a valid use case (Tails-privacy, Kali-pentesting) and some without (Hannah Montana Linux, ZorinOS and so on).

Linux Mint acquired popularity when Ubuntu decided to radically change its default graphical interface, proposing an Ubuntu clone + Cinnamon DE as default.

GNU/Linux permits to change the DE before and after the installation (it also exists an official Cinnamon version of Ubuntu) so Mint is useless, a copy of a copy, a waste of work.

I don't like suggesting good looking, poor maintained derivated distros.

As for a shitcoin it's (relatively) easy to fork but difficult to maintain.

So, don't do distro hopping, just do your customization.
