Which NCLEX Review Should I Purchase? Kaplan or Hurst

I wanted to know which NCLEX review to purchase....Kaplan or Hurst? Almost more than half of my class is taking Kaplan. Only a few are taking Hurst. Which is better and why? I want to make sure I spend my money well because, we are living paycheck to paycheck right now and money is really tight.

Also, is it better to take an NCLEX review with your class or better to study with people you don't know. I don't want to socialize. I want to focus and learn to pass the NCLEX the first time.

Thanks in advance!
