QEMU and Wine/Cornerstone are great little toys, but if you are not playing they are just not robust enough. Parallels Desktop Pro has all the features I need.
Before setting up widespread adoption in my Engineering team 5+ years ago I looked at Parallels and VMware was clearly better and smoother to use.
It is a lot better now, especially if you just adjust to the few changes in doing stuff in comparison to VMware. I now prefer it despite its more restrictive licensing. A lot of our engineers have multiple computers. VMware allowed a single license per user presuming they were on one machine at a time. Parallels requires per machine licensing.
