Verdict
The clearest difference is rating: OCO at 4.6 against Particle Escape's 3.8. OCO also leads on ratings volume (2.4K vs 12) and chart position (#165 vs unranked). Particle Escape's advantage is in-app purchases (none vs 8) and update cadence (every 4 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.
