But there is a difference in a place like Texas A&M or VTech versus some regular state public school.]
Heh. If you say so. You can add all the Corps fluff to try to make it more interesting or 'applicable' (it ain't), but in the end the NROTC program itself is identical to every other NROTC program in the nation. The VTCC or the A&M Corps don't hand out the commissions, no matter what their brochures say.
That said, it was certainly an experience, but you should know going in if you choose any of the senior militaries that it's not the real military. At all. Treating it as anything other than a military-STYLE student organization will 1. make you an enormous tool and 2. give you the impression that you somehow graduated from a 'better' program. I should know. I went to a senior military and was both of those for the first few months after I commissioned.
WHICH leads me to answer the OPs original question. What school's NROTC program is the best? Any variable you choose to rank will generate a different answer. Most commissionees? VT, Citadel or Texas A&M. Hottest women? Any Texas school. Best location? Washington or anywhere in southern California. Best instructors/curriculum? Hell if I know. This is an absolutely impossible question to answer, so I'd suggest you focus your inquisitive energies on finding the best UNIVERSITY fit for you and worry about the Navy stuff after you find a good fit, because if you hate your school, the Navy won't be able to do much for you.
