Verdict
The clearest difference is in-app purchases: Idle Gorilla at none against Cow Evolution's 12. Idle Gorilla also leads on iOS requirement (11.0 vs 15.0). Cow Evolution's advantage is ratings volume (24K vs 427) and update cadence (every 10 days vs every 6 weeks). On price, rating, ads and device support there is nothing between them.
