Verdict
The clearest difference is review sentiment: NumisQ at 100% against NGC's 6%. NumisQ also leads on rating (5.0 vs 2.2). NGC's advantage is update cadence (every 2 months vs every 30 months) and ratings volume (58 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
