I stick myself into developer test path. What I can guess is public beta has the same feature with the same develop beta released at the same time.Would the public beta version be the same in terms of features as the developer one? I would assume only the revision is different.
For this beta 1, you know, Apple will do it much better in the next beta version. But, once beta version is stable enough for daily use, you can use it as the daily driver.
It will be up to the individual. And without really knowing what the particular public beta will be like no one can really answer the question aside from just guessing/hoping one way or another.
