Each new device exists somewhat in a vacuum—it's a different configuration of parts each time, so each one will have its own perfections and imperfections. I am an iUP customer, so I see them every year.
The 13 Pro was the most "solid" device I've had since the 8 (I went 8, XR, 11, 12, 13, all Pros once introduced), I'll grant you that—but it was also the least "compelling" upgrade in terms of newness. Stability was its biggest pleasantry (my 12 Pro needed to be replaced once, and the battery degraded QUICKLY, so, not a good year), but that's because the tech in it was more of the same, and had more time to 'bake.'
The biggest pleasantry of the 14 Pro has been the Dynamic Island for me, but the back camera has been a lateral-if-not-overall-downward move. Definitely less good in dark lighting (for me) and the mode switching is awful as of 16.2. But that's because I'd suggest the hardware is on the sharp edge—it needs time to 'bake.'
Annually, the phone generations are less differentiated. I had my mother buy a 13 Pro on sale a few months ago, because it's a more stable device. I think it will "live" longer. Each one will be some steps forward, maybe some steps back, definitely some to the side. There's no real need to make an argument over which is "better," because overall progress moves forward. Just be happy with what you have—which you are, so, good for you.
