Verdict

The call

The clearest difference is review sentiment: CompTIA Security+ Exam Prep at 85% against O'Reilly's 46%. CompTIA Security+ Exam Prep also leads on rating (4.9 vs 4.7) and iOS requirement (15.0 vs 18.5). O'Reilly's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price, update cadence and device support there is nothing between them.
