I especially like the books with the wire bound spines.
Before ordering my books I print them out at home on regular paper, then put them together with scotch tape just the book will be. It's crude, but it helps to have it in your hands to see how things flow. It's different than the "virtual" book you see. Apple has a done a good job with the on-sreen book proofing - but nothing beats actually turning the pages.
I've been happy with my Apple Books too.
