Verdict
The clearest difference is price: Planet Fun at Free against AR Solar System's $0.99. Planet Fun also leads on rating (4.8 vs 1.0) and update cadence (every 4 weeks vs every 83 months). AR Solar System's advantage is chart position (#196 vs unranked). On ads, in-app purchases and device support there is nothing between them.
