I have been using ArchiCAD since V9.
and i am happy to say that the details and precision ArchiCAD is providing is much more higher than any other BIM tools.
Try using scale button with ArchiCAD by putting just any default Door and than change the scale to 1:20, now do the same thing with other closest competitor and mark the deference.
