I have a couple of nit picks:
They should really put a toggle switch for location services in control centre.
I use a five digit pass code. It's a compromise between a simple pass code and a more secure pass code. Why does the lock screen immediately turn off after entering a four digit pass code, but with my five digit pass code I have to press OK afterwards to unlock the screen?
Dictation still seems much slower after the upgrade.
