IMO there’s nothing about Arch, or any other distro, that makes it worth using, beyond whatever goals you have. If Arch helps you accomplish that goals, great. If not, pick a different distro that does.

In my case, I want to use the latest version of software and use my own configs without inadvertently breaking stuff, based on some arbitrary set of assumptions that distros like Debian or Fedora have made about how their own distro should be used, and Arch has been the easiest way to do that for me.

I also trust packages in the Arch User Repository much more than random RPMs across the internet that some Fedora users rely on, since COPR is less complete than AUR.
