Depends what is the host and the guest, Virtual box works pretty well on most hosts but the guest quality for Windows hosts is still questionably although it has generally improved.<p>If you need 3D acceleration especially with Windows guests then it&#x27;s pretty much VMware for either Mac, Windows or Linux or Parallels for Mac.<p>Performance wise VMware is still quite faster than VirtualBox in most cases and if you need to run a fairly complicated virtual network than VMware is pretty much your only the way to go.<p>When it comes to a Windows host if you have the pro version of Windows you get HyperV which as long as you don&#x27;t need a complicated network is actually better than VMware workstation in many aspects, it&#x27;s linux support is lacking but if you only run popular distro&#x27;s like Ubuntu you should be fine.<p>HyperV is much better in terms of performance in edge cases, and it also more gentle when it comes to power consumption so it won&#x27;t kill your laptop&#x27;s battery as much as VMware workstation.
