From what I understand, Clemson is more of a rhetoric program with a media sub-emphasis, whereas NC State is more of a communication/media program with a rhetoric sub-emphasis. The Clemson curriculum is more rhetoric-based and humanistic, while NC State seems to be more oriented toward media studies. The Clemson TA-load is pretty heavy, 2-2, while NC State's is 2-1 or 1-1. And from what I can gather, Clemson seems to be placing its students a little better, though NC State's students have more diverse assistantship opportunities. (As perhaps expected from the curriculum, Clemson's current students don't seem to be teaching anything other than Composition; but NC State's students, on the other hand, are teaching lots of different lower- and upper-division classes in both English and Communication.) That being said, both programs, despite their newness, have placed at least some of their very few grads in R-1s. That seems like a good sign.
I spoke with students from both places, and all were really enthusiastic.
Hope this helps.
