Verdict
The clearest difference is in-app purchases: Libro.fm Audiobooks at none against AuBook's 3. Libro.fm Audiobooks also leads on ratings volume (41K vs 1) and chart position (#90 vs unranked). AuBook's advantage is update cadence (every 8 days vs monthly). On price, rating, ads and monetization model there is nothing between them.
