Verdict
The clearest difference is review sentiment: AIR BUSAN at 39% against OTP라커's 5%. AIR BUSAN also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.6). OTP라커's advantage is update cadence (fortnightly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
