Verdict
The clearest difference is review sentiment: Emporia Energy at 69% against Sunnova's 6%. Emporia Energy also leads on rating (4.8 vs 3.9) and ratings volume (12K vs 844). Sunnova's advantage is monetization model (free vs ad-supported). On price, update cadence, ads and in-app purchases there is nothing between them.
