Verdict
The clearest difference is rating: OS One at 5.0 against Then's 4.7. OS One also leads on update cadence (every 4 days vs every 2 weeks). Then's advantage is ratings volume (24 vs 1) and iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.
