Verdict
The clearest difference is rating: USB Sharp at 3.1 against SwitchMemory's 1.0. USB Sharp also leads on update cadence (every 3 weeks vs every 5 months) and review sentiment (53% vs 31%). SwitchMemory's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price and device support there is nothing between them.
