ComiXology vs Kindle Unlimited

ComiXology has revolutionized the comic book and graphic novel industry by delivering a cloud-based digital comics platform that makes discovering, buying, and reading comics more fun than ever before. ComiXology’s reading technology transforms the comic book medium into an immersive and cinematic experience, helping comiXology become one of iTunes top 10 grossing iPad apps in both 2011 and 2012. Offering the broadest library of comic book content from the top 75 publishers, and including independent creators as well, comiXology will not stop until everyone on the face of the planet has become a comic book fan.

Amazon's subscription platform for e-books, audiobooks, selected magazines and periodicals, offering the largest selection (5 million digital titles) at a reasonable price (around $12/month). Kindle Unlimited offers many books in the $3–$8 range (if purchased individually) so if you read two or three books a month, the subscription usually pays for itself. Books can be read and listened to on Kindle e-readers or in the free Kindle app on your computer, tablet or smartphone. However, not all bestsellers or new releases from major publishers are available. The subscription operates like a "library" - you can have a certain number of books at a time (usually up to 20 at a time), return them and borrow new ones.
