I've used plus sized phones from the 6+.
6+, 8+, 11 Pro max, 13 Pro Max, and 14 Pro Max.
Last 2 iPhone iterations: I got the 13 Pro and 14 Pro. Had them for a month then gave them to a relative. Just missed the extra screen space and battery life. BUT I REALLY like the feeling of the Pros in my hand.
So right now I have the 14 Pro Max, but if I could easily go back to the 14 Pro and give it another try, I probably would. I admit I'm incredibly indecisive about this and it's not getting better.
Battery life comes at the cost of feeling like a brick in my hands. I have carpel tunnel so it really hurts if I hold the phone for too long. But the reduced screen space and battery dropping like crazy when only doing a few photos when hiking changed my mind with the 14 Pro to the 14 Pro Max. But I think knowing I could just hand this off to a relative encouraged my indecisiveness and action.
I do most of my reading on my computer. So I want my phone to be light and mobile. But I REALLY enjoy not having to worry about the battery and having every ounce of screen space when I want it.
