Good for you for doing your homework! That often doesn’t happen.
I went to Stanford a long time ago (early 1980’s) and loved it. I thought it was by far the best school in the country at the time, certainly for me, and I had strong exposure to both Harvard and Yale. Now, I’m not so sure, as CS has become the tail that wags the dog. That may not be an issue for you with your interests. I turned down Penn, and never really considered it in the same class as Stanford at the time; now, I’d give it serious consideration, and I personally might choose Duke over Stanford. But that’s just me, and I was never an engineering student.
Simplistically, I think that if you are engineering + business/entrepreneurship then Stanford is hard to beat. If you are looking for business/entrepreuneurship + engineering, or for more of an integrated program, then M&T is probably the way to go. M&T will also give you a more discrete community within the university. But either is a great option.
