You've really got me excited here...

What about NURBS for exterior architecture? For interior? Faster than SubD?

"If you're making a mechanical shape that can be created by some outline curves and also involves cuts and precise holes in it, then NURBS is not only way faster but also more precise (because cutting pieces with one another works better)."

So - if I wanted to make one of the Transformers from the movie - your description makes it sound like NURBS would actually be the only way to go for speed and accuracy...

What a great feeling - I am finally understanding all this stuff. :)
