Verdict

The call

The clearest difference is rating: USB Sharp at 3.1 against i's 2.3. USB Sharp also leads on review sentiment (53% vs 15%) and update cadence (every 3 weeks vs every 3 months). i's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price and device support there is nothing between them.
