I believe that Hurst is the best for content. Marly explains it in a way that makes you remember the content. I also used PDA, which is very very important. I purchased the 3 week course NCSBN and just did the questions (They have about 1100 questions) and viewed the rationale.
Passed with 75Q. In my exam, I found the PDA to be very, very helpful*** NCSBN touched upon some content that was actually in the exam and the questions really did help! Unfortunately, Hurst didn't help me in my exam but it might have been useful to other people.
Good luck! :)
