Hard disagree on where tech jobs are. If you want to work in tech for a Fortune 500 company in a non-tech industry, there's plenty in Alpharetta. All of the startups and companies that would attract the HN crowd are in Midtown / Buckhead though.
ATL is also home to the world's busiest airport. If you like to travel, it's a great city. You can fly direct to almost anywhere in the world.
