The clearest difference is rating: Spark at 4.8 against Idle Universe's 4.3. Spark also leads on in-app purchases (none vs 7) and ads (none vs shown). Idle Universe's advantage is ratings volume (1.5K vs 233). On price, update cadence, monetization model and device support there is nothing between them.
