I have used V Carve Pro (upgraded to Aspire) and I also at times use CamBam (horses for courses). Depending on what you are doing i would strongly suggest VCarve Pro as it has a much friendlier interface for set up and tooling. It also allows you to used shaped (ogee) type bits and create them in the tool bin. Both are very useful tools but for my two cents VCarve Pro works better. Both have a learning curve and CamBam once set up and the tooling set up for the operations you want can also flow rather quickly, but it does not have some of the CAd of VCarve Pro nor the amount of tutorials and structured training material.
