Came here to say the exact same thing. Manjaro has a history of issues and oddly provide their own repos (with differing packaging version to mainline Arch) when arch's repo + aur more than suffice.

On the endeavouros side they only have their DE customization packages + nvidia helper packages + ZFS + small helper applications (I'm assuming wgetpaste and such are for users to easily upload error logs, etc) https://github.com/endeavouros-team/repo/tree/master/endeavo...
