iPad is terrible for hand-writing. It's (relatively) heavy, so you can't hold it and write on it. It's slippery, and the friction between the pen and stylus is bad.

The pen itself also produces gigantic strokes.

The stroke size is highly customizable. What do you mean "the friction between the pen and stylus is bad"? As others have pointed out, you can get screen protectors and nibs for Apple pencils.
