Verdict
The clearest difference is in-app purchases: 惑星AR at none against GalacticAR's 3. 惑星AR also leads on review sentiment (100% vs 69%) and iOS requirement (12.0 vs 26.0). GalacticAR's advantage is update cadence (monthly vs every 7 months) and device support (6 vs 3). On price and ads there is nothing between them.
