It’s nice that Apple finally gave iOS owners a taste of the futility of homescree customisation that Android users have had for the last decade.
Changing icons is a waste of time. It only applies to the home screen and not the app drawer and certainly not at system level (eg in settings or the card view) which ruins the homogeny.
Android is equally messy in this sense: only OEMs like Samsung and Huawei let you change things at system level but only with the crappy icons on their respective stores. You have to use 3rd party apps if you want play store icon packs at system level but their integration is messy to say the least.
Widgets on Android are a mess because there is no design language between even Google’s own widgets. Apple’s widgets look nicer but lack interactivity. Plus if you want to quickly check the weather or batteries then you’re better off just sliding over the left hand screen rather than unlocking your phone, at which point an extra click takes you into the app with further details.
Your home screen is the hallway between the rooms on your phone which are the apps. Sure, you can decorate and hang some pictures but who spends any amount of time in a hallway?
