I'd think the massive calamity known as Atlanta traffic would be more off-putting than "living in the South". I know I'd love to find someplace warmer to live.
You might change your mind after spending a couple of summers here. ACs run 24/7. But 1" of snow sends everyone home - to clean grocery stores out of milk and bread.
If you know where you're going to work, it's not difficult to plan where to live to avoid traffic. Not to mention the breakneck pace we're adding midrise housing next to anything that looks mildly interesting.
Warmer but more humid. The Deep South is definitely air conditioning country.
You don't even have to be in the Deep South to need A/C. I live in North Carolina, which is "South but not Deep South" and I can't imagine living here without A/C.
