Biggest one for me would be the paged app drawer. I hate scrollig ones like you get on a Pixel and with recent Android versions and most 3rd party launchers don’t work that great. Also the AOD on Samsung phones is much better, the app quicklaunch and clipboard history sidepannels are really great, bixby routines can be useful and the whole quicksettings area is so much better with waaaay less padding and more useful toggles.
