Verdict
The clearest difference is in-app purchases: Engineering HandBook at none against PrepFE's 6. Engineering HandBook also leads on update cadence (every 2 weeks vs monthly) and iOS requirement (6.0 vs 13.0). PrepFE's advantage is rating (4.2 vs 4.0) and ratings volume (22 vs 4). On price, ads and device support there is nothing between them.
