Verdict

The call

The clearest difference is ads: Idle Exploration at none against Cosmic Synthesis's shown. Idle Exploration also leads on rating (4.3 vs 4.0). Cosmic Synthesis's advantage is update cadence (weekly vs every 3 weeks). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.
