Verdict
The clearest difference is review sentiment: STAR Interview at 100% against O'Reilly's 46%. STAR Interview also leads on rating (5.0 vs 4.7). O'Reilly's advantage is in-app purchases (none vs 1) and ratings volume (34K vs 4). On price, ads, device support and iOS requirement there is nothing between them.
