My parents are moving from North Jersey to the Philly suburbs on the PA side. They looked in Bucks, Montgomery and Delaware Counties before settling on a place in Chester County. If you live anywhere in PA that's within a reasonable commute from Center City you'll find the property taxes only slightly less than in New Jersey and your overall tax bill will also be pretty close. To me it's not worth the reduction in state and municipal services you experience in PA. That's the just the way I look at it, if you want to live in a First World state you should expect to pay First World taxes . . . and i've been living in PA for 7 years now.
People in South Jersey complain about the traffic, and it can get bad but compared to most other metros of a similar size (and even smaller) it's really not that bad on the Jersey side.
If you're trying to position yourself for an easy commute to Center City I would recommend Collingswood, Westmont, Haddonfield, Haddon Heights, Audubon, the area in Cherry Hill around the Woodcrest and Ashland train stations and the part of Voorhees around the Ashland train station.
These are basically the towns along the PATCO rail line.
PATCO :: Port Authority Transit Corporation
A few caveats, Collingswood High School is improving but isn't on par with Cherry Hill but the neighborhood (elementary) schools are golden and as a town, in my opinion, it blows CH out of the water.
Audubon and Haddon Heights don't have their own train stations but it's a short drive (2 miles or less) to the Haddonfield or Westmont stops.
Westmont is a part of Haddon Township. The other parts of Haddon Township are less desireable (aka - cheaper) but still part of the HT school district.
Haddonfield has some out of sight property taxes but you def. get what you pay for there.
As for living in Philly, some neighborhood schools are good. Some high schools, like Central and Masterman, are some of the best in the country and better than any school in the suburbs, but good luck on the waiting list. The more family friendly neighborhoods in the city are in the far northeast and in the northwest. In the northwest it's East Falls, Roxborough, Mt. Airy and Chestnut Hill. The property taxes up there range from $2000/yr to $4000/yr depending on which neighborhood/how expensive the house. Easy train rides into Center City.
Also, If you live in this neighborhood in West Philly your kids will go to the Penn-Alexander school. It was already a gorgeous neighborhood but prices there really shot up since they introduced the school. Still might be in your price range, though.
here is a link to some pictures of the neighborhood . . .
