I used Dr. Strauss's book for the MPJE and passed with a comfortable amount of room even though I've never worked in NJ.
I've used both Dr. Strauss's book and Dr. Cutie's packets for various exams.
Both have pros & cons:
Dr. Strauss: more law text, over 1300 questions, online ordering with PayPal, fast shipping, but more expensive ($168).
Dr. Cutie: more charts, easier to read at a glance, more tips/tricks, do's/don'ts, cheaper ($135), but mail order form with check/money order, slower shipping.
It comes down to your learning style. If you are a question/answer learner Dr. Strauss is it. If you learn by making your own study materials and charts go with Dr. Strauss. If you get nothing from the studying process and just want pre-made at-a-glance charts & lists go with Dr. Cutie.
