Personally, we prefer Kent. My hubby works in NY, but the kids and I just moved to DE from central NC so this area is just right up our alley. Depends on what you're looking for; DE is quite unique in that the northern county is more metropolitan, the southern county is quite rural, and the central county is a good mix of both.
We do like our school district, which is Caesar Rodney SD. But I am quickly hearing lots of good things about many more districts throughout the state. If our first 4 months here are any indication, we won't be calling u-haul anytime soon! I'm so confident in that, I'm putting a lot of flattened boxes out for recycling every week. Or at least the weeks the wind isn't going to blow the boxes to MD!
