Not sure what "digital architecture" means these days, but I would say UMich shines for digital fabrication (robotics, 3D printing, etc) workflows, with a very nice shop. Then again, that comes with a price tag... if you don't care about working with robots, you still have to pay for it. I haven't seen Sci-Arc's shop.

No real difference in teaching quality private Vs. public - there are some very well-funded, or well-managed, public schools. The main difference between schools is more personal than general - is your professor a person who can help you get connected to and prepared for the side of the profession you would like to enter? Research the faculty at each school you're interested in, and see if their work and personality appeal to you.

Both have lots of facilities for fabrication. I think UMich has pulled away lately though. The program at Michigan is a little more balanced between west coast and east coast ideas. If you go there you don't have to focus on fabrication or scripting. SCI-Arch is a little more heavily about that, and is the epitome of west coast design approach. 

I'm biased but I like UMich better. Funding is a big issue too, and generally I think Michigan comes out on top. If you are in state it's much cheaper, but given that you are international both schools probably would cost similarly. The difference is that in my experience UMich gives a lot more scholarship money, but that's a matter of your offers from them. 

Thanks for replying JK2k and natematt, but I am really worried about the fact that SCIArc not being a University. The fact that its just an independent school makes me question the credibility it will offer me after joining.
