Verdict
The clearest difference is rating: AIR BUSAN at 2.4 against Trinity Airways's 1.0. AIR BUSAN also leads on review sentiment (39% vs 13%) and monetization model (free vs free with in-app purchases). Trinity Airways's advantage is update cadence (fortnightly vs monthly). On price, ads, in-app purchases and device support there is nothing between them.
