Verdict
The clearest difference is price: Ebook Reader Pro at $5.99 against USB Disk Pro's $99.99. Ebook Reader Pro also leads on update cadence (every 4 days vs every 3 months). USB Disk Pro's advantage is rating (4.5 vs 2.0) and ratings volume (142 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.
