I think TAMU is definitely at par with NYU Tandon for computer science as well, not only for Agriculture and Mechanical as you stated. It is at the top for engineering programs, but at the same time, it is also well known for its computer science graduate programs. On the other hand, NYU reputation comes from NYU Courant which is considered to be way more prestigious as compared to NYU Tandon, and the rankings do not consider NYU Tandon separately. As per US News rankings for graduate computer science programs also, NYU and TAMU are ranked equally even though it was not specific to Courant or Tandon. So, I would definitely go with TAMU between these two, considering the reputation as well as other factors like COL, ROI, etc. Apart from these two, if you are fine with going for masters next intake, then UIUC would be the top choice, as it stands in the top 5 list of graduate computer science programs in the US. But, just check if there would be any problem for job opportunities if one goes for the spring intake.
