Verdict
The clearest difference is rating: Visionauta at 5.0 against eSpeak's 4.1. Visionauta also leads on review sentiment (100% vs 67%) and update cadence (every 3 days vs every 10 months). eSpeak's advantage is ratings volume (21 vs 2) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
