If you want an Arch-based system with less worry about updates, have a look at Manjaro. The team do a pretty decent job of making sure each batch of updates work together - though if you use the 'stable' branch you'll be a week or two behind Arch stable (but not for security updates). If you want it more frequently, Manjaro's 'unstable' is synced to Arch stable.

Yes, Manjaro has a small team and occasionally mess up the website, but don't let that stop you from trying the distro.
