Verdict

The call

The clearest difference is in-app purchases: O'Reilly at none against DataCamp's 10. O'Reilly also leads on ads (none vs shown) and ratings volume (34K vs 4.8K). DataCamp's advantage is review sentiment (72% vs 46%) and iOS requirement (15.1 vs 18.5). On price, rating, update cadence and device support there is nothing between them.
