You are choosing the wrong objects for your test.----We all sit with our newly purchased lenses and camera bodies in an "easy chair" and snap photos of the junk in that room---which is mostly about sharp focus. That is not a good test. It is the ambiance and total handling of the light and colors which is the test. One highly noted master photographer of the 1940s and 1950s said he never read reviews but merely took a roll out of his NYCity office and looked at it.

In your comparison take photos of people as portraits for you comparison. Not junk on the other side of your easy chair. Then make the comparisons. What I have seen with cheap P&Ss and Phone cameras is people's skin is mostly smoothed and washed out. Often it improves their appearance and they love it. But they do that even with children and not just the old people. So---make a real test and not just the easy comparison which is the result of built in algorithms.-------------ew----(The only reason to use a phonei is convenience in candid shots of family and friends.)

I've got an iPhone 12 Pro, and am in no hurry to upgrade to a 14. My wife is even less interested, because she has the smaller 12 and the 14 doesn't come in that size. (We only upgraded from the 10 to the 12 because we got an upgrade offer that was too good to refuse.)

I probably use the iPhone more for casual shots, in large part because it's already in my pocket. My Canon T6i is what I grab when I want higher resolution, precise control of aperture, speed or lighting or greater magnification, eg, macro work. (I'm not all that impressed with flash photos on the iPhone, but I don't take a lot of them.)

The landscape photos I've taken on the 12 seem better than the ones I get with the Canon, but I don't have an ultra-wide lens.
