Verdict
The clearest difference is update cadence: SincoOTA at every 3 weeks against Engraver's every 4 months. SincoOTA also leads on review sentiment (50% vs 23%) and rating (2.8 vs 2.5). Engraver's advantage is ratings volume (23 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
