Verdict
The clearest difference is rating: GCLS Mobile at 5.0 against ACE Library's 2.6. GCLS Mobile also leads on review sentiment (40% vs 3%) and update cadence (every 3 weeks vs every 5 months). ACE Library's advantage is ratings volume (36 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.
