I use the larger iPad pro - I understand it's quite expensive but that's the only Apple device we have for our home and me and my wife use it for our own purposes and we find it to be worth the money. She uses it mostly for art while I use it for reading and taking notes - the split screen view is a really amazing with a PDF open and a note taking app (I use OneNote).

The iBooks app is also good for taking notes on the PDF - I usually use it to take notes of papers but prefer to use OneNote for the books.
