I went from a 15 Pro to an Air and then back to the 15 Pro. As much as I liked the Air (the supposed "compromises" in terms of battery, camera, speaker did not bother me at all) I had to go back to the Pro as the Air was just too wide and big for me to handle comfortably and was causing pain in my little finger.
Shame though as I really liked the Air, as much as iOS 26 and the glass look has been maligned it kind of seems like a really good fit for the Air
