There is no doubt that Emory is a better B-school. I have admits from 4 schools as of now - UW, UIUC (Illinois @ Urbana-Champaign), GaTech and Simon.
I chose GaTech, because they gave me a graduate assistantship and also align with my psot-MBA goal of IT/Consulting. What I have gathered from my research on B-schools is that after the top 10-15 schools it is really up to an individual to get where he wants to, and even after an MBA, the school's name is going to only take you so far.
I guess your choice should be based on what are your post-MBA goals. If you want to get into marketing/finance - Emory would be a better option. But if you want to head towards IT/Consulting domain - Georgia Tech would make sense.
Hope that helps.
