I cannot speak for any of the verticals, but I do agree with Sinc, that I've found 2010 to be a great release in regards to stability, features introduced as well as their freedom of bugs... though I have seen no need to investigate the use of parametric drawings, so that's a large lapse in my judgment of new features... I mainly speak on the handfuls of more minor introductions.
I've found that the material browser, when working in 3D, even seems more stable. I'd had it cause crashes and fatal errors before, and sometimes when closing and re-opening a drawing, it would forget some materials and reset them to a copy of "Global", whatever Global was set to. I have not seen ANY of this in 2010. I can only hope that the lengthy times I spent talking to Autodesk technical support engineers giving them information was put to use
Of course I'm sure I'm just a speck of raspberry jam on their radar, but it's a nice thought to think that maybe I helped, lol.
