Verdict
The clearest difference is in-app purchases: Spark at none against Echo Planet's 2. Spark also leads on ads (none vs shown) and ratings volume (233 vs 23). Echo Planet's advantage is update cadence (every 3 days vs every 3 weeks). On price, rating, review sentiment and monetization model there is nothing between them.
