Verdict

The call

The clearest difference is rating: Octopus Evolution at 4.8 against Slime World's 4.1. Octopus Evolution also leads on review sentiment (93% vs 60%) and ratings volume (4.1K vs 64). Slime World's advantage is update cadence (every 2 weeks vs every 6 weeks) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
