Verdict
The clearest difference is rating: Kill Sector at 5.0 against Mars Quest's 4.0. Kill Sector also leads on in-app purchases (none vs 5) and ads (none vs shown). Mars Quest's advantage is ratings volume (91 vs 4) and update cadence (fortnightly vs every 6 weeks). On price and device support there is nothing between them.
