Verdict
The clearest difference is in-app purchases: Solar System Clock at none against Explain 3D's 1. Solar System Clock also leads on update cadence (every 2 days vs every 5 months). Explain 3D's advantage is iOS requirement (10.0 vs 16.6). On price, ads and device support there is nothing between them.
