Same here. I mean, occasionally there's a frame drop here and there but it happens at roughly the same rate as it did when my 6 had iOS 8.x.x. I'd say the most serious "issue" is that animations/transitions still take a lot longer than they should, and as far as I can tell you can't trigger any action while the transition isn't finished. i.e. you press home to go to the home screen and while the home screen is appearing you can't press an app icon yet.
