My point is, no one ever has any way of knowing what the final beta is. People thought that 9.2B4 was the final beta before the GM, but it turns out that B4 was the GM. And just because you have had bad experiences with betas does not mean thats the norm. I've ran every single beta of every single version of iOS since 9.0, and all the betas of 7.0/8.0 and have never experienced any catastrophic bugs. Battery drain here and there, a little lag here and there, but nothing that prevents usage of the device.Of course the final beta is going to be the most stable...
