Verdict
The clearest difference is price: Documents at Free against USB Disk's $0.99. Documents also leads on ads (none vs shown) and update cadence (weekly vs every 3 months). USB Disk's advantage is device support (4 vs 2) and iOS requirement (12.0 vs 16.0). On review sentiment, in-app purchases and monetization model there is nothing between them.
