BS. t.u. and A&M are ranked about the same in both undergraduate and graduate business and engineering. t.u. might have a slight edge in liberal arts, and it DOES have an edge in its honors program. And t.u. has a slight edge in law schools. Of course, A&M doesn't have one, but...
A&M has medical and vet schools on campus, which t.u. doesn't have. Also, anything Ag goes A&M by default. I think A&M generally is seen as having the edge in things like education (i.e. preparing teachers and administrators), sports training, management, and kineseology, and several professional scientific fields like meteorology. At this point, both schools are seen as top rate and there isn't much difference unless you are looking at a program only one has (like graduate library science, t.u. only).
