Verdict

The call

3D Solar System and Astronomy Game both sit at 4.4 stars, but that hides the real split: 86% of Astronomy Game's written reviews are positive against 29% of 3D Solar System's. Astronomy Game also leads on ads (none vs shown). 3D Solar System's advantage is update cadence (fortnightly vs every 13 months) and ratings volume (1.7K vs 10). On price, rating, in-app purchases and monetization model there is nothing between them.
