Just so you know, I'm an OOS first-year ME, so I can't speak with much experience or be discipline-specific for you.
Negatives: first, the positives far outweigh the negatives. The only negatives I can think of is that if you're a dorm room hermit that doesn't socialize easily, then this may not be the best place for you, as you have to do all the work in earning a social life (and there definitely is one; there really is absolutely no excuse to be bored in Atlanta). This IS a school for nerds and you WILL find plenty of them, but so far I've had loads of fun and the educational quality is fine (but again, first-year, can't say much atm). Oh, also apply asap for housing, and if you can easily accomplish the above statements, I wouldn't recommend freshman experience, but it's not a bad idea either. The only real bonus is that there are tutors in the FE dorm basements (but you can find way more at the library).
Advice: I'm sure you've heard it before, but college is completely different from high school. If you have the initiative, you'll find that you can do almost anything you want here on your own. Again, no reason to be bored here. Talk to people, and make friends fast.
