Line-weight, in my experience very few BIM objects in Revit. Revit 'families' is as close as it gets. The reason is that it is not in AutoDesk's or the manufacturer's interests to do so. Vectorworks has a much more 'parametric' basic 'generic' core of objects that speeds up production in line with design practice. Revit 'prefers' designers to be too specific too early. VW opts for updating information during the design process, which is how as an architect I work. Revit prefers the designer to insert and replace with specific products even before they've been specified.
The very reason I rejected Revit as my BIM software of choice in the first place. But, as ever, hype succeeds over common sense.
