Quite impressive when they shot at 48MP, but the pictures taken at 12MP just look like your bad, few generations old, non-pro iPhone photo. As a very amateur photograph that doesn't want to carry his DSLR all the time I considered getting it for the 48MP but after reading the review and seeing what would be most of the pictures I would take (the 12MP ones), it's a hard pass.
I'm upgrading my iPhone 13 mini because having switched from a Pixel 4a, the camera performance is just unacceptably bad. It's a testament to how much I like the rest of the iPhone that I didn't just go back to the pixel. I briefly considered carrying the Pixel around just to take pictures.
The one downfall was that when I broke my screen this year, the replacement was so costly that I ended up switching to a friend's unused older model iPhone for now. I may still repair it at the end of the year...
