Verdict

The call

The clearest difference is ratings volume: iUSB Pro at 1.1K against i's 23. i's advantage is update cadence (every 5 weeks vs every 3 months). On price, rating, review sentiment and ads there is nothing between them.

i ships an update every 5 weeks, iUSB Pro every 3 months. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
