Neither CachyOS nor EndeavourOS get out of the way same as Manjaro. CachyOS doesn't even ship with app store by default, which is an immediate yuck for someone who needs a "just conveniently works out of the box" distro.
Manjaro is the only Arch derivative that allows you to never even think you have Arch under the hood. It has all sorts of QoL improvements and graphical settings for everything, it has a smooth and beautiful integration of all package sources (something Arch is notoriously bad with), and if you don't need AUR, package delay prevents breaking changes, helping you not to think about managing your system.
Manjaro is not for everyone, and it will definitely not satisfy a typical Arch demographic, as it's made with different people in mind. Hence such an opinionated take on your side. Recent management issues don't help, either, but that's exactly what they're trying to take action against.
In any case, it was Manjaro that served as my gateway to Linux, and it couldn't have been smoother. No other distro I played around made me feel confident in switching.
