That's my neck of the woods. Take a look at South Forsyth county, just over the line from Alpharetta. My address is Cumming, but the other side of the street is Alpharetta. Lower taxes (though not like they used to be), absolutely awesome schools.
For all intents and purposes, I live in Alpharetta/John's Creek, with the advantages of Forsyth. Three of Georgia's top ten elementary schools are in Forsyth County, three of the top twenty high schools, two of the top four middle schools (and three of the top ten). When you take out the magnet/charter/specialty type schools, that's pretty amazing. Even if you don't have kids, that's great for home values and tells you a lot about the community.
Which is not to say the schools in Alpharetta/Milton are not quite good as well, because they are. But I'm really blown away by the quality of schools and students at my kids' schools, all three levels.
Roughly in the general area on this map just north of McGinnis Ferry is what I'm talking about. I think some of this area has a Cumming address, some of this is Suwanee address. You're kind of right in an intersection of Milton, Gwinnett and Forsyth counties, with great access to the best of all three counties.
