Shortly after posting that I ran into a different Microsoft field engineer. I thought of this thread and even showed him the video in the first reply
He thought it was funny but had a much more focused explanation and comparison, also explaining why the other Microsoft tech said that vSphere only aligns to 4.1. It's because the comparison is fundamentally unfair because Hyper-V by itself is extremely limited. The reason for this, however, is that it depends on SCCM and subset components of SCCM for all advanced features; Powershell DSC, for example, directly competing against Chef/Puppet, being a subset of the massive SCCM suite.
SCCM is also very hard to test since there is a lack of evaluation opportunities. Microsoft does have its version of Hands on Labs though, and it was also explained to me that if you join the Microsoft Developer network for a few hundred dollars then you can have access to it. I'm also interested in hearing the answers to your questions. Sorry no bites yet.
