This is our experience as well. When we were doing residential work it was nothing to sit down and completely work up portions of a large project right there with the customer. A massive massive sales tool for us. Now in the commercial work we do the same thing. After our shops are in, we can meet on-site with the crew and show them in 3D what the work entails. They love seeing it in 3D and being able to ask for a different view or perspective, a certain section view that wasnt in the shops. We can show them in real time and simply export a pdf or jpeg and shoot it right to their on-site Ipad or computer.
I really despise the subscription based format that everyone has gone to now because just like with SU they simply keep creeping the price up every year (including the maintenance) and soon we will be paying the same numbers that a seat for Autocad use to be. But it is what it is. At this point I would be hard pressed to be without it. We run all our casework through a paid plug-in Cabinetsense that handles the entire CNC side as well so a single job will pay for the lot.
