Additionally, as an educator in NJ, I can tell you that the sites listed below are your first step in gaining insightful information on school districts, with the state website being the best as it will give you the true test scores, class size, etc. without the "spin." The next step would be accessing the websites of both districts, specifically the sites of the schools to get information regarding classes, curriclum, sports, extra-curricular activities, etc. Finally, some districts will provide you with information if you contact them directly. I will be closing on a house soon in Ocean Cty, and I contacted the school directly after doing my own research. The administration of the school happily and readily scheduled an appointment for me to come in for a tour of the school to gain first hand information. This definetly helped in my decision of placing a bid on my home, as we were torn between two towns because of the great school systems. (Also, we do this occaisionally in my own district, only because not many people call to ask. Those that do are given the opportunity!)
In my opinion, the answers you may receive for this type of question may be biased based on the person's personal experience with the school district. The best pieces of information are factual data from the state education website, feedback from community members and educators within those districts, and whatever first-hand knowledge you can get.
