I need to install and run Windows 10 as a virtual machine on the latest Debian Stable (9.5). I would much, much rather use a free (as in freedom) GPL-licensed software doe that.
(I know, I see the irony too, of running the definition of proprietary software but still insisting on GPL for the virtual machine software... But it's better than dualbooting, as it'll allow me to use Windows even less this way!).
But I have very little experience installing and working with a virtual machine (once installed Windz7 with VirtualBox) and have little support from people around me (our "computer person" is great and willing to help, though also has very little experience with this).
In your experience, is any one of these two any better, i.e., easier to install and get to work, and allows the virtual OS to run fast and without freezing or misbehaving? Or is there another one not listed there you'd recommend?
