I'd say he didn't do his research properly.

First, we have been there long before OpenVZ, so the
'well seasoned' listed there is dubious.

Second, we are (now) based on cgroups and namespaces,
so the summary there is wrong as well.

Further ...
 - we have python bindings as well
 - there are some (outdated) panels
 - I would definitely consider it more stable than OVZ :)

But obviously it is biased (towards Docker) and just
takes the fact that OVZ now is owned by Parallels as
a 'sign of stability' :)

Completely correct. Whenever some mainline feature gets
useable, we try to incorporate it as soon as possible.

I don't think you've made the wrong choice, but obviously
I'm biased as well :)
