Verdict
The clearest difference is rating: Summer smiles at 5.0 against LEO's 3.6. Summer smiles also leads on review sentiment (80% vs 40%) and monetization model (free vs ad-supported). LEO's advantage is update cadence (every 2 months vs every 17 months) and ratings volume (67 vs 2). On price, ads, in-app purchases and device support there is nothing between them.
