I have the iPad Pro 11 (218) with Pencil 2. I use it with the GoodNotes5 app. My experience is It can fully substitute paper & pen and even better in Easier to undo anything or to erase You can re-arrange the things on paper (e.g. you can insert an extra row or paragraph you can move a graphics easily on the page you can move a paragraph to the next page you can re-arrange the order of paragraphs etc.) You can easily switch between colors (and much faster than with normal pen) You can change the color of a paragraph at any time You can insert a photo or a graph (e.g. from the net from a PDF or you can make a photo) There is OCR in the app so you can search (I don use this feature but I think it works) You can have extreme colors or page designs. E.g. sometimes I use black pages with white and yellow pen. It is beautiful. You can have all your notes books with you at any time (for PDFs I rather use Readdle PDF Expert) TL;DR the iPad+Pencil is better than the real paper and pencil in every respect (expect in direct sunlight or when the batteries are low 3 but it never happens with the iPad as it has a huge battery).
