Verdict

The call

The clearest difference is rating: Spark at 5.0 against Blu e's 4.4. Spark also leads on review sentiment (100% vs 60%) and update cadence (every 8 days vs monthly). Blu e's advantage is ratings volume (5 vs 1) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
