hello, for those who have bought the 15 (or the Pro), are the pictures finally better than iPhone 11?

I had an XS and ‘upgraded’ to a 13 Pro, but have been very disappointed by the over processed images so held off upgrading my partners 11 because she needs photography for her hobbies,

She has said the phone is starting to chug though, ran out of storage long ago, and battery doesn’t last a day anymore, so I am considering a replacement

Will 15 (or Pro) disappoint? Is the computational stuff finally not ruining photos? or should i try to eak out another year?
