The clearest difference is rating: Mars at 4.8 against Mr. Crab's 4.1. Mars also leads on review sentiment (91% vs 73%) and ratings volume (22K vs 1.1K). Mr. Crab's advantage is ads (none vs shown) and iOS requirement (8.0 vs 12.0). On price, in-app purchases, monetization model and device support there is nothing between them.
