Verdict

The call

The clearest difference is rating: GCOO at 2.9 against KORAIL+'s 2.3. GCOO also leads on review sentiment (46% vs 11%) and ratings volume (153 vs 15). KORAIL+'s advantage is update cadence (every 4 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.
