Verdict

The call

The clearest difference is price: Documents at Free against USB Disk Pro's $99.99. Documents also leads on update cadence (weekly vs every 3 months) and ratings volume (626K vs 142). USB Disk Pro's advantage is in-app purchases (none vs 15) and device support (5 vs 2). On ads there is nothing between them.
