I'll start by saying NJ sucks politically, legally, etc. I live here, I should know.
However South Jersey is a bit of a different state then Northen or Central NJ. Population is much lower, property is cheaper, things are generally more laid back. The southern part of the state is generally more conservative, rural and more gun loving then the northern side. Traffic is not bad.
Our gun laws suck badly so if you own firearms, make sure they meet our stupid laws (basically think 90's assault weapon ban rules).
There is a lot of outdoor in that area, with the Pine Barrens and other state parks being a nice place, but be aware of ticks, we have lots there. I'd stay away from Vineland proper and I would avoid getting to close to Atlantic City, so I would look north and north west of Vineland, towards Mullica or Glassboro .
Be aware that you be living between 3 different Nuclear plants (Salem, Oyster Creek, and Hope Creek) and some of these are really old.
