I agree that it is fully capable of producing professional quality work, given that it's professional adoption has been relatively small as to date. 3D packages take years of investment in training to master and once one masters a suit they are hesitant to switch. The dogma in 3D packages can be worse than language dogma. For good reason as well, with languages some amount of foundation transfers but with 3D packages how one accomplishes a task differs from UI to UI, it is closer to starting completely over. When I left 3D as a career I had one of 2 choices buy a full license for a commercial package(and an SGI at the time, Wavefront had just become Maya and the windows version was in the works) or learn Blender. I chose the latter it really was starting over but I eventually became as good with Blender as I was with Wavefront (now Maya).
