I believe that both GT and Purdue attract recruiters at the national level, so they are the same in my mind in that regard. They are both highly ranked, very close to each other. On the most recent NRC survey, Purdue was ranked 31 and GT was ranked 33, an insignificant difference. These rankings are for faculty quality mostly for graduate programs. However, these rankings have some influence where recruiters go.
I would say that the biggest factor in determining YOUR outcome is how well YOU do at either school.
If money didn't matter, then it's a tossup which you like better. However, since $92K is obviously very meaningful to you, I think you need to pick Purdue.
It certainly can't hurt you to ask GT for more money in light of your Purdue package. You'd be crazy not to. However, depending what state you live in, $92K is like two years of take home pay on your first job!
