Quick suggestion - iPhone(15/16 )vs Samsung(s24/ultra) vs Google pixel(9/10)

Hi geeks, I am from India and using a android phone since I got my first phone. I am now looking to upgrade it from premium smartphones like

iPhone - iPhone 15 or 16 (not sure about this) --> not a big fan of Apple ecosystem it will be the last choice for me --> reason : hefty costly maintenance as compare to other flagship premium phones.

Samsung - S24 or Ultra from long time want to try samsung. --> kind of lean towards it want to try it out 😉 Maybe the first choice phone.. --> Reason : but having the fear of getting the green lines over it.

Google Pixel - New phone and excited about it.

Pricing - Having 35K in hand now and can arrange as per the suggestions for the phone's.

Note - Using Oppo Reno 8T from since 2023. Not aiming for 85K + price range.
