I tend not to be a negative person, but there are some obvious visual stuff with DP8 - stuff that Apple could have and should have fixed - stuff like inconsistencies in functionality of slider switches in Settings, missing app icons in Settings menus, stuttering, etc. None of it would be "show stopper" level, but it screams "half-@$$ed development". With that said, I'm generally quite pleased with the liquid glass theming, and have it on my daily iPhone and iPad.
If you can overlook the nits, I say "go for it". If you can't overlook the nits, the RC/GM/GA releases won't impress you, either.
