I was quite curious to compare Bootcamp vs VMWare as well. Pretty equivalent for this particular task
I decided to do Parallels and Bootcamp (not a requirement for Parallels but you can do it if you want). Only reason I did Bootcamp was to play the occasional windows-only game. For most other things, Parallels or VMWare should do the trick. I'm guessing VMWare on the Mac is like VMWare that I've used previously, where you get a workspace windows. Parallels is like VMWare except you don't get a separate windowed environment, it seems more integrated into OSX. And this is just me playing around with Parallels so I don't know all the features.
