On apple, the animations are slicker, the hardware much better, and arguably the software stack higher quality. The Bluetooth audio quality was noticeably better on every device I used, from old car to brand new stereo.
But the always on display isnt as good, focus modes didn't work quite like I wanted, widgets are less powerful, the notifications UI is inferior, and accessing system settings is more cumbersome.
Bonus: the lightning port is inferior.
So yes. I would love the android software architecture with apple hardware and privacy.
