iPhone 16 vs iPhone 16 pro

I am upgrading my iPhone from an 11 and are wondering if I should buy an iPhone 16 or 16 pro. I want a phone I can use for many years and have a good battery capacity. I also like to take pictures for memories and are going on a few concerts this year so I want a good camera. Is it worth it to invest in a 16 pro or is it not a big difference between the 16 and the 16 pro?
