Verdict

The call

Mars and Alien Invasion both sit at 4.8 stars, but that hides the real split: 91% of Mars's written reviews are positive against 40% of Alien Invasion's. Mars also leads on iOS requirement (12.0 vs 15). Alien Invasion's advantage is update cadence (every 10 days vs monthly) and chart position (#141 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.
