Verdict
The clearest difference is rating: Colonize at 4.6 against Mars's 1.0. Colonize also leads on in-app purchases (none vs 11) and review sentiment (40% vs 20%). Mars's advantage is update cadence (weekly vs every 5 months). On price, ads, device support and iOS requirement there is nothing between them.
