Verdict
The clearest difference is rating: Decimator at 4.3 against Givebacks's 3.4. Decimator also leads on review sentiment (56% vs 38%) and iOS requirement (8.0 vs 16.4). Givebacks's advantage is update cadence (every 3 weeks vs every 9 months) and ratings volume (53 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.
