I believe this is subjective to each individual in terms of schools and communities of what is best.
Here is a link that might help you with regards to school
Hope that helps....
I grew up in the Lutherville/Ruxton/Riderwood area of Baltimore County and I loved it. Incredible recreation/sports league system and amazing public school system. Riderwood Elementary, then Ridgely or Dumbarton Middle, then Towson or Dulaney High School.
There are fantastic private schools in Baltimore as well, including Gilman, Bryn Mawr, Roland Park and St. Paul's, just to name a few, but Maryland has one of the best school systems in the country, so there area many many options. If you want to know more about any one specific part of Maryland, I can help you.
