The Kindle Oasis has a premium price tag that can be a hurdle for budget-conscious users, but the eBook reader benefits from an innovative design and excellent screen. The Kindle Voyage earns its top-in-class marks thanks to its stellar build quality and software options. With Amazon's deep library of books and content options from third-party publishers, the Voyage remains the eBook reader to beat for its competitors. Similarly, the Kindle Paperwhite has many of the same software strengths as the Voyage in a more affordable package. The eReader even uses the same 300 ppi screen as its higher-end counterpart.
