Verdict

The call

3D Solar System and GalacticAR both sit at 4.4 stars, but that hides the real split: 88% of GalacticAR's written reviews are positive against 29% of 3D Solar System's. GalacticAR also leads on ads (none vs shown) and device support (6 vs 2). 3D Solar System's advantage is ratings volume (1.7K vs 116) and iOS requirement (16.0 vs 26.0). On price, rating, update cadence and in-app purchases there is nothing between them.
