How is the surface line for writing code using a pen? I hear they are the best note taking devices but does that apply to code too? What are some other options

How is the surface line for writing code using a pen? I hear they are the best note taking devices but does that apply to code too? What are some other options for writing code? What I'm looking for: 1) natural writing feel 2) low response times 3) easy erasing (software) 4) optional: Digitization/handwriting recognition
