Verdict
The clearest difference is review sentiment: Sol Explorer at 100% against 3D Solar System's 29%. Sol Explorer also leads on rating (5.0 vs 4.4) and in-app purchases (none vs 12). 3D Solar System's advantage is update cadence (fortnightly vs every 171 months) and ratings volume (1.7K vs 6). On price, device support and iOS requirement there is nothing between them.
