They were pretty good. Or at least the applicative parts of their courses (labs, projects) taught us a great deal at the time. I'm not sure how they were in their professional life outside the university. Actually, I lie. Two of my colleagues worked for one of them for a short while. I remember them saying they had to work a lot there but also learned plenty of new things. One of them later worked for Google in the US, but later returned to work for a company closer to... home, I suppose.
