Again you seem to think the only point of Manajro or Endeavour are to make it easier to install Arch.
It is.
Plus you have offered no reason to use Endeavour over Arch
Yes I did -- it has a GUI installer. That's the only reason.
Please note I have not noticed stability or security issues to a greater degree than I have on any other distro that isn't ultra-stable (e.g. Debian Stable)
