Verdict
The clearest difference is rating: EPA VSAT at 5.0 against SonicExpress's 3.5. EPA VSAT also leads on update cadence (fortnightly vs every 2 months). SonicExpress's advantage is ratings volume (11 vs 1) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
