Advice Request Samsung OneUI 4.1 vs OnePlus OxygenOS 12.1, Which is better?

I actually stopped using other launchers in Android and I'm keeping juste OneUI. It quickly restores your preferences from your Samsung cloud backup when you get a new phone. It's not as smooth as what Apple does with the IPhone but still saves a lot of work.
