You've got to see NJ to make up our own mind.
I've lived here most of my life and attended Rutgers in the early '60s. Diversity is the keyword. Diversity in terrain, people, attitudes, income, lifestyles, etc. You can live in a semi-rural area or in the heart of the 'hood. Jersey has it all! It's quite expensive, as was mentioned before, so plan on spending about $400-$700K for a good house in a decent neighborhood with a pretty good public school system. If you have school-age children and can't afford/don't want private school, you can forget about living in the main cities, such as Newark or New Brunswick because the inner city public schools are not exemplary. I would recommend a lengthy visit before you plant your feet.
