I haven't used it, but it seems like a thin wrapper over Arch so it should work pretty well.

If you don't want to tinker but want a rolling release, give OpenSUSE Tumbleweed a shot. It has a lot going for it that other rolling releases tend to either not do or leave to the user, such as:

• BTRFS snapshots configured automatically - if an upgrade goes bad (pretty rare), you can do a snapper rollback and try the upgrade later
• OpenQA - the devs write automated tests when there's a problem, so breakages rarely repeat
• YaST - system settings management, so you don't need to learn all of the CLI tools for things like firewalls or user admin

And packages are usually about as new as Arch, sometimes newer. I used Arch for ~5 years and Tumbleweed almost as long, and Tumbleweed seems to work better for me (less manual intervention, less breakage, etc). If you want a custom package, it doesn't support the AUR, but it has a user repository that has pretty much everything I wanted from the AUR anyway.

Arch is great if you want to tinker and make a super customized setup, but if you just want newer packages, OpenSUSE Tumbleweed or Fedora is probably a better option.
