Verdict

The call

The clearest difference is rating: GCOO at 2.9 against KORAIL+'s 2.4. GCOO also leads on review sentiment (46% vs 11%) and ratings volume (152 vs 11). KORAIL+'s advantage is monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs fortnightly). On price, ads, in-app purchases and device support there is nothing between them.
