Upgrading from iPhone 13 Pro — 16 Pro or 17 Pro for wedding BTS/content creation?

I’m currently using an iPhone 13 Pro and it’s starting to struggle....battery drains quickly and sometimes the camera doesn’t even open properly.

I shoot weddings and want to start offering BTS / content creation (Reels, short videos, behind-the-scenes) for couples and planners, so having a reliable camera and good video performance is important.

I’m looking to upgrade and deciding between:

• iPhone 16 Pro
• iPhone 17 Pro

For those using iPhones for content creation, is the 17 Pro actually a noticeable upgrade in real-world use, or is the 16 Pro already more than enough?

Also....would you recommend 256GB or going higher for this kind of work?
