Verdict
The clearest difference is rating: DeerPhoneCase at 2.5 against E's 2.0. DeerPhoneCase also leads on review sentiment (23% vs 0%) and ratings volume (31 vs 4). E's advantage is update cadence (fortnightly vs every 5 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
