What is the best CAD program?

Many detonators use 3-D computer images to achieve the most accurate demolition plan possible. There are hundreds of CAD programs available for this purpose, but which is the best? To name a few; Autodesk, AutoCAD, SolidWorks, KeyCreator, TurboCAD, and Revit. The Silicon Valley AutoCAD Power Users (SVAPU), which is the world's largest local AutoCAD user group, presented Revit with their "Best of the Best CAD Software" trophy. Revit was tested among many of the leading software programs, and was given the reward based on ease of use and a "nice intuitive feel". The program is mainly used for 3-D structural, mechanical, electrical and plumbling (MEP) engineering. I personally have only had experience with KeyCreator in my Engineering Design class. I found it to be simplistic enough for a first-time user, yet complicated enough for the professional. My professor who was PE described it as being "just as useful as AutoCAD minus all the confusion". I'm looking forward to exploring new programs in the near future.
