Buford schools are great. High School looks like a quality small college campus with an equally impressive football program. Hell of a drive to work though, particularly during rush hour. Easily could be 2+ hours.
Kennesaw/Marrietta area is the "value" play. Great schools, good amount of quality new build homes coming on the market for $700-$900k at reduced rate financing from builders. Ton of Delta pilots with young families moving into the area.
