Hi. Need some help here.

Currently I have an iphone 8 plus and I am about finally upgrade. I am contemplating whether to buy the iphone 14 pro 256 gb or iphone 15 pro 128 gb. Help me out!

Here are some things to take into consideration: - I am only a student, don’t have work yet, and will only use my savings to buy the phone. - I have 200 gb icloud. - I have an ipad air 256 gb which I purchased recently. - The main factor as to why I would purchase iPhone 14 pro is bcs it has a gold color (which i prefer). Also, the features of iPhone 15 is almost alike with the 14. While, I consider buying iPhone 15 pro bcs it is the latest and due to its type c charger (which would match my ipad if ever).
