Zumdahl Vs.Raymond Chang

Okay, so I’m having a difficult time deciding what textbook to buy to review for the placement test to get into AP Chem. The placement test will be next month and I haven’t been studying… Anyways my two options for the textbooks are Chemistry Edition 11th Raymond Chang or Chemistry Edition 7 by Zumdahl. I heard that the AP textbook for chemistry is the one y Zumdahl but I also heard the Raymond has better explanations over some topics. Which one do you guys think is better?
