Verdict

The call

The clearest difference is review sentiment: Kaigyo at 100% against LINE's 14%. Kaigyo also leads on rating (4.9 vs 3.2). LINE's advantage is ratings volume (18K vs 203) and update cadence (every 9 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
