i got the 14--upgrading from a 12 mini. I actually went with the Pro at first, but exchanged it for the 14 because it felt very uncomfortable to hold for any length of time. I'll miss the Pro cameras but that's the only feature of the Pros that I really care about. Dynamic Island actually felt like a downgrade in terms of usability--it means you actually get less usable screen space than with the regular iphone. I turned off AOD after a day--I have a watch, and I can just tap the phone screen to wake it up anyways, so also not a very useful feature. I never notice the screen refresh rate difference--the 14 feels very smooth to me. So coming from a mini the 14 was the better compromise for me between size/weight, battery life and screen size. The day Apple comes out with a super light Pro I'm gonna be the first in line but until then I'll probably have to stick with the base iphone.
I didn't really think about getting the 13, though--I haven't really looked into the differences, if any, between the 13 and the 14.
