Verdict

The call

The clearest difference is update cadence: Monster Evolution! at weekly against Zoo's every 3 months. Monster Evolution! also leads on iOS requirement (12.5 vs 15.0). Zoo's advantage is review sentiment (69% vs 57%) and chart position (#112 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.
