Hi there.. Looking to finally change my Huawei P20 pro after so long...below are the few flagship phone under consideration... Could any1 recommend me which 1 is better?

1) Samsung galaxy s21 ultra
-problem is hard to find snapdragon and also pricey... But most pages that I visit also recommend this becoz it's currently the top android phone

2) oneplus 9 pro
-nvr use before so I'm not sure about the performance & reliability... Can any1 commend?

3) oppo find x3 pro
-same nvr use before but attracted to it's camera...can any1 commend?

Currently only survey these 3 becoz lazy to consider more..

My main purposed is gaming & camera for take photo my children...

Thanks for any1 input
