AppleInsider and Apple strongly advise that users don't install beta operating systems or beta software onto what they deem "mission-critical" or primary-use hardware. Instead, they should retain backups of their data and try to use secondary hardware that isn't as essential to maintain.
For general users wanting a less risky experience, Apple typically brings out a public beta version of its updates shortly after the developer counterpart. A more battle-hardened version of the update, with potentially fewer bugs or issues, it is the version that interested members of the public should try, not the developer build.
