ReceptionRating · Positive reviews · Number of ratings

B737 MRG holds the better App Store score, 4.9 against 4.7.

Written reviews complicate that: 81% of B737 MRG's written reviews are positive against 100% of iTrain B737MAX's, so the app with the better star average is not the one people write more warmly about.
