I use Zenmate Desktop. I use VPN occasionally to browse blocked sites. Never tried torrent so dont know Zenmate support torrent or not. On my 4mbps connection speed seems good. For my use its good, simple & light. Clear GUI & no bloats like ads blocking, tracking, malware/phish protection, etc...
Have tried OkayFreedom Premium & it too seems good speed. Connecting & disconnecting takes little time.
Have tried Freedome VPN Trial from Fsecure & seems good speed.
Have tried Cyberghost Free & speed seems good. Needs .Net 2 or 3.5.
Have tried Avira Phantom Free & speed seems good. Installs Avira launcher & cannot be uninstalled.
Dont know about privacy & torrent for the above VPN.
