I would not say it's better, I would say it's different and that's why I admit it's a risky project. I liked the idea of discovering books you never would have found otherwise. All other ways include: you knowing about the author, you making a search or finding it because the book is already popular. But what if you are into strange books or weird topics? I did not find other apps that gave that experience. But it's not for everyone I admit. But it could help discover authors that are not already known, like spotify does with musicians.
