I've had my iPhone 13 PM since Monday, upgrading from a 11PM. I am struck every day at how good the battery life and screen are compared to the 11PM. I could charge this thing once every two days and have a lot of room to spare. The screen is bright, sharp, and animations are extremely smooth with Pro Motion. Looking at older pictures is a joy on the screen. The camera is a huge step up, with 3x zoom being a joy to use early in my testing.
In contrast, when testing the 12PM, I was struck at how similar the experience was relative to the 11PM. The UI, screen, and capabilities of the phone were more or less unchanged from the 11PM. Sure, the form factor was better, and the zoom on the camera got a little bit better, but otherwise the phone was the same. And you took a hit on the battery life. Frankly, this applies to the regular 11 to 12 as well - aside from the switch to LCD, the 11 was a great phone that offered two good cameras, strong battery life, and fun colors. The 12 didn't improve on that all that much. The 13 adds back the strong battery life and a big improvement in camera (though the 11 is still a powerhouse).
Even the 13 Mini is a dramatically better buy than the 12, as you get useable battery life and the same camera improvements.
TLDR - it is almost never the right move to get the iPhone with the "form factor change" - it is usually better to wait until the next, more refined iteration, which is what the 13/13P/13PM
