The clearest difference is rating: Osmo World at 3.9 against CodeGamer's 2.5. Osmo World also leads on ratings volume (1.3K vs 52) and review sentiment (42% vs 30%). CodeGamer's advantage is update cadence (every 4 days vs every 2 months) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.
