ElementaryOS has nothing to do with Red Hat or Arch. It’s Ubuntu LTS with a custom macOS-like desktop environment called Pantheon. Being based on Ubuntu LTS means packages only get updated every two years, so they can be a bit old. Debian has the same problem, tho. If you like macOS, you might want to use it. Otherwise, you might not. Worth noting that Pantheon is available on distros other than ElementaryOS (but not Debian).
