Verdict

The call

The clearest difference is review sentiment: Space Gate at 86% against 3D Solar System's 29%. Space Gate also leads on ads (none vs shown) and rating (4.8 vs 4.4). 3D Solar System's advantage is price (Free vs $12.99) and ratings volume (1.7K vs 200). On in-app purchases, monetization model, device support and iOS requirement there is nothing between them.
