Subgraph was started in part based on concerns with Tails that the authors might be too nice to pursue publicly. I'd personally be wary of both projects.
If you really need to not have your ID leaked, like the UAE recently going after dissidents with state malware, you'd want to use something like Subgraph with a seperate firewall/NAT internal address as insurance (pref running OpenWRT or a BSD not the default proprietary lighthttp server 'admin portal' firmware running with full privs).
