I have been using VW for 5 years. early on I used SU to flesh out concepts and use for basic presentation. After a year or two I dumped SU to perform all 3D work in VW. VW has become more intuitive in recent versions although still not as simple as SU.
I had to balance the time and found the translation from SU to VW too time consuming.
There was a little pain getting up do speed, however can now say that the time efficiencies are better from go to woe. Plus the benefits of a more professional output.
To really add some bling and if the project warrants it, I export to Artlantis to producing final renders.
Attached are a couple of images after Artlantis processing. Note that this was my first attempt.
