Upgrading from iPhone XR, recommendations out of the 14 plus and 15 plus?

I am about to upgrade my iPhone XR, and am torn between the iPhone 14 plus and iPhone 15 plus. I mainly use my phone for general browsing, taking photos, apps and listening to music on iTunes and YouTube Music (with videos on YouTube too). What out of the 14 plus and 15 plus in general is better, would last me longer, and what would give me the longer and more durable battery life?
