I find myself both equally satisfied and dissatisfied with each size. I have a 14 Pro Max, and I love the large display and battery, but the ergonomics aren’t great. I love the Pro size, but the battery life isn’t enough for me (though battery life was enough for me on iOS 15 on the 13 Pro - iOS 16 ruined the Pro model’s battery life). I’ve always been very tempted by the Mini because of the ergonomics, but the battery life definitely wouldn’t be enough for me, it’s missing Pro features I really want, and I think the display might become frustrating in day-to-day usage just due to feeling cramped and too small to see comfortably.
The Pro model would probably be my best all-around model for me if it had close to the battery life of the 13/14 Pro Max. But then again, I really enjoy having a huge display on the Pro Max. 🤷
