Verdict
The clearest difference is review sentiment: Captain Nemo at 87% against Secret Island's 34%. Captain Nemo also leads on rating (4.6 vs 4.3) and ratings volume (3.6K vs 347). Secret Island's advantage is update cadence (every 3 weeks vs every 22 months) and iOS requirement (8.0 vs 13.4). On price, ads, in-app purchases and monetization model there is nothing between them.
