Verdict

The call

The clearest difference is update cadence: Opal Chat at every 2 days against Lek's every 3 weeks. Opal Chat also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 77%). Lek's advantage is ratings volume (83 vs 6) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
