Motorola’s software is a lot less intrusive. Off the top of my head there is not a single important feature I can think of which is locked behind a Motorola account (though I am yet to get the Android 14 and Hello UI update, so I’m not sure if that changed things), whereas Samsung forces you to create and login to a Samsung account to access many of the features which make One UI so customisable. You can disable/uninstall/not create an account to minimise data leakage but then you’re missing out on some of the stuff which makes Samsung phones particularly good (like Good Lock).
