Verdict
The clearest difference is update cadence: Solar System Clock at every 2 days against Celestial Dances's every 30 months. Solar System Clock also leads on device support (3 vs 1). Celestial Dances's advantage is iOS requirement (9.0 vs 16.6). On price, ads and in-app purchases there is nothing between them.
