I hope you are happy with the Sony but not everyone would agree that their cameras are the best though some rate them highly. You are still welcome to share you views in the Lounge for instance, not sure if you have any other Samsung products. There are also more modern devices than the Note 20 and new line up will be likely be unveiled in February. Personally I have not had a Sony Mobile though have experienced some of their other products.
There are different opinions but Digital Camera World are impressed with the S21 Ultra. https://www.digitalcameraworld.com/uk/buying-guides/best-camera-phone
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
