I disagree regarding Android. Google's Android feels to me like it's trying to go against everything that makes Android good such as SafetyNet, Android 12 removing customizability from Android 11 and choosing default apps convoluted, separating gestures and launchers, half assed tablet experience.
One UI has a lot more customization and practical options and generally always implemented features before Google did, like split screen and still can do things no other OEM can.
Is the amount of screen being occupied by 3 button navigation bar really that big? It's a few lines of text at most.
