• AUR isn’t a reason to switch to Archlinux. It is a necessary “evil” when the officially maintained and tested software is not available in the repository. On the flipside, the cool thing is it allows easy system integration of any custom package. That’s actually a really cool feature if you need it, but not a specific reason to switch to the distribution. Software availability is also changing with Flatpak and Distrobox and similar stuff.

    Other distributions have similar repositories in place too, at least with similar goals to extend the official repositories with user packages. Ubuntu has this PPA (which is not very good BTW) and Fedora has Copr in example.
