I had a play in an Apple Store last week with the 16 Pro and Pro Max. I was certainly leaning towards the PM due to the bigger screen and knowing it has the longest battery life possible. Also taking photos will be more enjoyable due to the size and streaming media etc. The battery life does frustrate me with my current iPhones as cannot last even one day without top up charging.I got the 6 Plus, and I’ve had the largest iPhone that I could get ever since then. I was going to switch to Android and get a Galaxy Note if Apple didn’t ship a large phone. I’ve flirted with going back to the smaller iPhones, but I returned them and got the Max. I love the bigger screen for reading, photos, videos, everything. It’s never been uncomfortable or bulky to me. I don’t have big hands, and I use the large phones easily.
All that said, you’re just going to have to try it for yourself.
