Out of the three counties you mentioned, Morris is the most safe, green, and tax-effective one. It is also the wealthiest and, in my opinion, the friendliest.
You will feel perfectly at home in Chester or Mendham, especially if you like horse-back riding, hunting, or gardening. These are very upscale (and pricey) places with true small-town atmosphere. Chester is a real countryside while Mendham has more “suburban” feel. Also, Chester has a very nice downtown area with lots of antique shops that New-Yorkers just love to visit.
The schools here are superb; both towns share the high school. Chester school science fair is recognized as the best on the entire Atlantic coast.
You can drive to the nearest city, Morristown, from Chester in just 25 minutes (15 minutes from Mendham). From Morristown, you can reach New York City by train in only 45 minutes. Another train station is located in Gladstone (5-7 minutes from both towns), but train ride to NYC from there is longer, about an hour and half.
There are many major corporate sites in the area, including Pfizer, AT&T, Verizon, to name just a few. You can find plenty of jobs here, especially in the IT or financial services field.
Since Chester is located 800 feet above the sea level, the summers here are very cool compared to the central NJ (we rarely use air conditioning), but the winters are also colder. Both summer and winter temperatures are about 10 degrees cooler than in the center of the state. And our snow is 2 inches thicker
Chester was recently profiled in NY Times:
