Have been using the iOS and MacOS betas since day one without a problem as my day to day devices. There are certainly bugs and crashes here and there but no deal breakers. However, I wouldn't recommend it for most anyone, since when things do break I can easily find work arounds, where the average person may not, and if compatibility for something you rely on breaks then you are out of luck if you don't have extra mac laptops or phones to work on. These betas are far more reliable than previous years. To note, you have a typo in your title. "macOS" is a thing, "MacOS" is not.
