The clearest difference is review sentiment: Engine Sounds at 100% against Gun Build N Run's 36%. Engine Sounds also leads on in-app purchases (none vs 10).

Gun Build N Run holds the better App Store score, 4.6 against 2.8.

Written reviews complicate that: 100% of Engine Sounds's written reviews are positive against 36% of Gun Build N Run's, so the app with the better star average is not the one people write more warmly about.
