The sharp edges are exclusively an issue with the Framework 16 due to the spacers that allow you to change the alignment of the trackpad. It's definitely been one of my main annoyances with my F16 that I didn't experience with my F13. I've been scratched by them and had my arm hair caught and pulled.

However, Framework has already indicated that they are looking into providing an input module that spans the entire width of the device to eliminate the need for the spacers.

I don't really know what the "creaking screen" is about though. IMO the F16 screen and hinges are a higher build quality than the F13. I had to upgrade my F13 hinges to the 4kg hinges to keep it from bouncing and moving.
