Verdict
The clearest difference is review sentiment: Mars at 91% against Radiation Runner's 30%. Mars also leads on ratings volume (22K vs 308) and rating (4.8 vs 4.6). Radiation Runner's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
