I have both and I think that PWN is better for those who are starting the prep, while College Panda is more advanced. PWN Guide should be a complement for the Official Guide, whereas the Pandas Book is independent. Therefore, if you did not already do the official material, the PWN might be really good by helping you with the errors that will be made in the CB Practice tests. If you are done with official prep, Panda
s book is BY FAR the best out there.
