Best AP Review Book?

Hey guys, next year I am planning on taking AP Psychology and AP Language. Because I want to do well on the tests, I have decided to order review books for them. I was wondering, which one is best? Kaplan vs The Princeton Review? I looked online but could online find the reviews for them relating to the MCAT, which isn’t helpful. I have temporarily preordered TPR 2018 books, because I heard they are better, but am open to changing that. What do you guys think, or what experience do you have with the books?
Thanks!

Personally, I’m partial to Princeton Review- I don’t have any experience with Kaplan.

I hope you get more opinions in this thread!

In general, TPR beats Kaplan. This being said I only have experience with WHAP and AP Gov, but have a look at the Amazon reviews, I use them when deciding whether to buy Barrons/TPR/Kaplan/Other
