Get the iPhone 15. It has the same 48MP main sensor as the iPhone 14 Pro but images are 24MP instead of 12MP in the 14 Pro. You will miss a 3x telephoto camera so if you think that is important for you go for the iPhone 14 Pro
iPhone 15 also gets USB type C although USB 2.0 speeds but yeah less cables to carry around
iPhone 15 Pro for 250 euros more gets you a titanium frame which most people don’t need and that’s about it
So imo the best bet will be the iPhone 15
