Verdict
The clearest difference is rating: NthGrow at 2.4 against Mars Legacy's 1.3. NthGrow also leads on review sentiment (33% vs 12%) and update cadence (fortnightly vs monthly). Mars Legacy's advantage is ratings volume (71 vs 8) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
