Which one are you using for your production environment?
Personally, I always found that VS is much easier to set up for my needs (mostly labs, tests, demos and so on). One of the most annoying aspects of VMWare for me is the complexity of their network setup and configuration. I’m sure I don’t know as much as I should about VMWare, but it always seemed a bit too cmplex for my needs.
