I ran more than a few Manjaro installations for myself and family, and still do. Despite what others say, I've had very, very little problems with it and maintenance has been low, users just run Octopi every once in a while and it just works.
I've since moved my own systems to Fedora because I just find it more useful for development, but I would still use it over vanilla Arch, which I ran for almost a decade before Manjaro. Can't really speak to Endeavor, but as far as I know it's basically bleeding edge Arch with the ups and downs that implies.
And whatever the stupid shit the Manjaro team has perpetrated over the years, they've still built a solid distro.
