At least for Antergos its a super fast way to get a "real" Arch install. Sure I know the process of creating partition tables, formatting drives, bootstrapping wireless and what not, setting up system time, adding a bunch of services I want, etc. But for anyone that likes the Arch release process (and thus isn't interested in Manjaro) and AUR it was a place to point them without the massive learning curve because nowadays it generally just works.
