Verdict
The clearest difference is review sentiment: 100 moment at 80% against 1/2 one's 50%. 100 moment also leads on iOS requirement (12.0 vs 16.4). 1/2 one's advantage is update cadence (every 2 months vs every 17 months). On price, ads, in-app purchases and monetization model there is nothing between them.
