The PinePhone has a 6" screen, the Pocket Reform has a 7" screen. That's enough to make a noticeable difference for sure, but it's not incomparable, especially considering the PPKB goes to the very edge of the device and the Pocket Reform has an obvious bezel.

The PinePhone would have far less usable screen real estate[0]. 6" diagonal with an 18:9 aspect ratio would make landscape use almost a non-starter. The Pocket Reform is 7" diagonal with a laptop-like 16:10 aspect ratio.
