Verdict
The clearest difference is in-app purchases: Unlucky Rocket at none against Project Clean Earth's 16. Unlucky Rocket also leads on iOS requirement (13.0 vs 15.0). Project Clean Earth's advantage is update cadence (every 3 weeks vs every 25 months). On price, ads and device support there is nothing between them.
