I actually think Duke has the superior NT faculty. Richard Hays, Mark Goodacre, Joel Marcus, Doug Campbell, etc - pretty tough crowd to beat. On top of this, the resources at Duke are pretty amazing. If you have any interest in early Christianity, you have J. Warren Smith, Lucas Van Rompay, and Elizabeth Clark. Emory's big early Christian guy (Ayres) moved to Durham (UK). On top of this, you have UNC right down the road. I know people in the Religion program are able to go take classes at UNC, but I'm not sure about the Div school (I don't see why not, though). That opens up classes with Zlatko Plese (Coptic specialist), Bart Ehrman, etc.
Durham is also a very affordable place to live with plenty going on. I would go to Duke.
