It depends a lot on the teachers imho, the difference is chalk and cheese, I did my degrees before the internet. I had some math teachers that in hind sight weren't very good, I found this out many years later watching Gilbert Strang teaching linear algebra amongst others. In CS though I was lucky enough to have a couple of lecturers that wrote the books on the subject, the depth of knowledge they had was huge (as you'd expect). To be a crotchety old man - you youngsters have it so easy now :-) - you can watch the experts in any field teach it, even ask them a question, the stuff of dreams. So I think because of this the value of a masters coursework is a lot less than it was, at least in CS.
