Unlike previous generations, the pen tip when Surface Surface is less rounded 3 Pro smooth and not as strong. In my case, this circumstance causes the matting so that the pin the film is easily scratched and squeaks when drawing with a higher pressure rating. (Comparable to the chalk squeaks on the blackboard)
Although Matteriung is implemented very pleasant, I'm going to buy a crystal clear film. This seems to me to be the best compromise for pen input.
Edit: I have now received the crystal clear sheets. They are in my opinion, despite the lack frosting better suited for pen input as the matt films. That the matting is intended to provide a more similar paper writing experience, I can not confirm personally.
