I would describe F360 as a good 3D CAD package with a pretty good integrated CAM package. I use F360 for design, and then it is pretty natural to just carry on with the CAM module. On the other hand, if I want to do something fairly straightforward I might well do it in VCarve (just cut-down Aspire...) because it quick and easy. No need to use F360 just for CAM, I would have thought.
