NaturalReader is a long-running product that handles a genuinely wide range of documents, and for a lot of people that breadth is the point. For listening to books it has two catches: the better voices are metered by the day, even after you have paid, and making audio needs a connection at all. PhonoLeaf generates the voice on your phone, so there is no quota to run down and nothing to lose when the signal goes.
The differences that actually change your day, rather than every line on both feature lists.
