Need advice on where to move in north Georgia?

Hello. We are going to try and move back to Georgia next year and old friends have told me how much towns have changed outside of Atlanta. (as far as crime skyrocketing in a lot of areas) I grew up in Rockdale County which I've heard has gone downhill. What areas would you recommend? I just want an area that is lower in crime, but not a fortune to live in, with decent jobs available. I have not been back to Georgia in 16 years since we moved to Illinois so I have no idea what certain areas are like anymore. Does anyone know what College Park is like now? Thankyou for your help. : )
