Verdict
The clearest difference is review sentiment: K at 100% against MSE OS's 0%. K also leads on rating (5.0 vs 1.8) and update cadence (every 2 months vs every 29 months). MSE OS's advantage is ratings volume (5 vs 1) and iOS requirement (9.0 vs 13.4). On price, ads, in-app purchases and monetization model there is nothing between them.
