Verdict
The clearest difference is review sentiment: USB Fusion at 100% against USB Sharp's 53%. USB Fusion also leads on rating (5.0 vs 3.1) and in-app purchases (none vs 6). USB Sharp's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (18 vs 1). On price and iOS requirement there is nothing between them.
