Verdict
The clearest difference is rating: Cast at 5.0 against Comic Book Viewer's 3.8. Cast also leads on update cadence (every 10 days vs every 3 months) and review sentiment (100% vs 71%). Comic Book Viewer's advantage is ratings volume (135 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.
