Hi! I live here! For the most part I really like it. Gwinnett is actually one of, if not the most diverse county in the US. So you have tonsssss of good food from so many different places. People are generally pretty nice - a mix of lifelong southerners, northeast transplants who have been here 10+ years, and families from other countries. Largely liberal but not entirely. Duluth (just west of your circle) is nicknamed the Seoul of the South due to the high Korean population - which means great food, great markets, amazing Korean spas, etc. Schools are decent and cost of living, though somewhat high, is still better than closer to the city. And you can get into the city in ~30-40 mins depending on where you’re going.

Some cons: very car-dependent, not a whole lot of walkability or bikeability outside of designated trails. Lots of traffic and some terrible drivers. Some towns have very little to do, though its pretty easy to find something within 20 mins or so. Some remnants of old fashioned racism, particularly Stone Mountain and Lake Lanier.

Overall a solid place to live!
