First of all, thank you for clarifying that TorVM is a gateway and not a workstation. derp. I’m trying to multitask (one drawback of Qubes 
) and I got things turned around in my last post.
However… your assessment about TorVM and Whonix may not be so cut and dry. The current Debian template maintainer for the Qubes team seems to think that the TorVM is every bit as good as the Whonix configuration and could possibly provide privacy benefits because whonix has a smaller pool of users. Of course, he could be wrong but he seems to know what he’s doing. He also clarified in a post from this year that TorVM is nt depreciated.
