Verdict
The clearest difference is rating: Wi at 3.0 against USB's 2.0. Wi also leads on review sentiment (50% vs 18%) and iOS requirement (7.0 vs 13.0). USB's advantage is update cadence (every 5 weeks vs every 4 months) and ratings volume (29 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
