Verdict
The clearest difference is rating: Mavie at 4.8 against Euki's 4.2. Mavie also leads on review sentiment (100% vs 70%). Euki's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (163 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.
