Verdict

The call

Defender II and Space Outpost both sit at 4.2 stars, but that hides the real split: 71% of Defender II's written reviews are positive against 17% of Space Outpost's. Defender II also leads on ratings volume (1.1K vs 34) and iOS requirement (12.0 vs 15.0). Space Outpost's advantage is update cadence (weekly vs every 5 weeks). On price, rating, ads and in-app purchases there is nothing between them.
