Verdict

The call

The clearest difference is ratings volume: 737 Handbook at 247 against EASA Part 66 Modules Exam's 2. 737 Handbook also leads on update cadence (every 3 weeks vs every 6 weeks). EASA Part 66 Modules Exam's advantage is review sentiment (100% vs 87%) and iOS requirement (13.4 vs 16.4). On price, rating, ads and in-app purchases there is nothing between them.
