Verdict
The clearest difference is review sentiment: Next Numbers 2 at 88% against 3D Solar System's 29%. Next Numbers 2 also leads on ads (none vs shown) and rating (4.7 vs 4.4). 3D Solar System's advantage is ratings volume (1.7K vs 31). On price, update cadence, in-app purchases and monetization model there is nothing between them.
