My university made us take a 3 day 9am-5pm Hurst review class, with the online review as well. I think it was beneficial to get your CORE knowledge down. Don't know about price though. I think Kaplan is more about testing strategies, I haven't tried it personally though.
I completed the Hurst review and took the q-trainers from Kaplan that are circulating on the internet. I felt that if I understood the core content, I would be better able to answer the questions. This strategy worked for me as I passed NCLEX, the first time in 75 questions. Many of my classmates took Kaplan and also passed boards in 75 on their first try. It is purely a matter of preference. Many people would advocate for doing a zillion questions-- while I did all of the Kaplan q-trainers and Hurst q-bank questions, I didn't do a ton of questions (less than 2,000)... The key is understanding your strengths and weaknesses so that you spend time reviewing your weaknesses and don't waste time studying things you know!
