The reason this is better is because their ebooks are DRM-free. Not so with Safari's books. When you use the download tokens from Safari, you get a book that is riddled with watermarks and legal threats on every single page. When I'm reading a book having a legal threat with my name embedded in it at both ends of every single page is extremely distracting and makes the book nigh-unreadable. I let my download tokens expire on purpose because what you get with them is garbage.
