Verdict
The clearest difference is review sentiment: myQQ at 49% against Sunnova's 6%. myQQ also leads on rating (4.8 vs 3.9) and ratings volume (26K vs 844). Sunnova's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.
