there's a few really good ones but alot of them have issues with not being upgraded to support A11/Oui 3.1
it's partially a major reason that the S21 series can't use swart switch without throttling your phone and burning battery amongst other things
source, forums here, samsung and various Google searches on same and similar issues.
Nova is still the best as far as I can tell right as @deadpool3049 also mentioned but yeah the A11 version update is in beta:)
alternatively. there are some amazing skins and themes available for these phones to make do until apps get properly updated to the new OS
