Verdict
The clearest difference is rating: WE Catalog at 5.0 against Aufmaster's 4.3. WE Catalog also leads on iOS requirement (17.6 vs 26.0). Aufmaster's advantage is update cadence (every 3 weeks vs every 9 months) and ratings volume (4 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
