Pros
Excellent institution for a STEM BS/MS/PhD degree - especially for those who are aiming to go into industry. Consistently ranked in the top both nationally and internationally. Excellent resources for research with a very diverse group of researchers. Huge career fair, and generally a lot of companies coming through campus to recruit. For in-state students the ROI is pretty astronomical (i.e. I made it through a BS and PhD with ~$20k student loans, and general PhDs leaving my department expect ~$90-100k salary).
Cons
The fees for graduate students are a constant source of frustration. Most grads can expect stipends in the mid $20k range, and then expect to pay $1200 for fall/spring fees and $1000 for summer fees. Tack onto that $750 parking permits, and it gets to be a bit much for those of us commuting everyday. Also, for commuters specifically, traffic in Atlanta is pretty awful sometimes.
