Verdict

The call

The clearest difference is rating: T at 3.8 against CoreNexa's 2.3. T also leads on review sentiment (53% vs 22%). CoreNexa's advantage is update cadence (every 3 weeks vs every 4 months) and ratings volume (256 vs 45). On price, ads, in-app purchases and monetization model there is nothing between them.
