Verdict

The call

The clearest difference is rating: CLZ Comics collection database at 4.9 against iComix's 3.2. CLZ Comics collection database also leads on review sentiment (91% vs 55%) and ratings volume (15K vs 58). iComix's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 3 days vs every 11 days). On price, ads, in-app purchases and device support there is nothing between them.
