Verdict
The clearest difference is rating: Binnacle School at 5.0 against Nautical Ship Flags's 4.6. Binnacle School also leads on update cadence (weekly vs every 3 weeks). Nautical Ship Flags's advantage is ratings volume (15 vs 1) and iOS requirement (15.2 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
