troutspinner,
I also had the question of which software to use for my firm a few years ago. I had some AC experience and no VW experience. We had just moved to the Mac platform (although I was not letting that dictate my choice). To make a long story short we chose VW, and after a little time with the software we became quite fluent with it.
My over all impressions with VW are that the software will do everything I want it to do with the ability to produce more creative , personalized and artistic drawings and renderings than with other software. Where the weaknesses are VW has consistently improved and overall is a very robust system.
And Christiaan is right kudos for not letting price determine choice.
