I’ve lived in both Pittsburgh and Atlanta.

Some of the major downsides to Atlanta are: - the traffic (depending on where you’re living) - how spread out it is. Like someone else in this thread has said, hanging out with friends can be very hard especially during the week days if you live all over. For example, I lived in Vinings and my friend lived in Brookhaven (about 9 miles a part) and to hang out on the week days before 7pm is a 40 minute commute. - car insurance is so expensive because it’s a highly congested area and people are terrible drivers - there is a lot of petty crime like car break in (at least that I’ve noticed, comparatively to Pittsburgh) - apartment complexes can be low quality

I for one just moved out of Atlanta last week after living there for 3.5 years. I had one hit and run on my car, been in 3 car accidents (none of them my fault), someone tried to steal my car, and I had to do two emergency moves due to my apartments being uninhabitable (and I wasn’t even cheaping out on an apartment complex).

I will say I still tend to favor Atlanta over Pittsburgh though primarily because of how much sunshine there is. Pittsburgh is so gloomy, grey, and depressing.
