I can't really answer if it is the same info on other books because I haven't really read the other books. Obviously, I'm sure you know many of the things it says already. I think the only "new" things might be the cycling methods, like I said. But that alone is worth the entire book. If you know how to plan your macronutrient ratios in each meal, according to your target calorie intake for the day, how much fat and what types of fat you should eat in every meal, how much protein you should eat according to your body type and goals, the carb cycling method, and the calorie cycling method already, you probably don't need this book.
Also, the book explains the reasons why you should do what is suggested in the book. For example, why you should eat protein every two and a half to four hours. The reasons themselves motivate you to do the things right, always.
When I bought it, it was only $39. I don't know if the price has increased.
