The clearest difference is rating: JSON Navigator at 5.0 against Source 3's 4.3. JSON Navigator also leads on update cadence (every 2 weeks vs every 2 months) and review sentiment (67% vs 44%). Source 3's advantage is ratings volume (10 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
