First of all, I really appreciate the dark appearance with the gradient which is easy on my aging eyes. I’ve been trying to dial in a dark look with the Appearance sliders in previous version of Cubase. Very cool that it’s the default look in C7.
I love the large meters with the range of metering scale options as well as the scalable faders and Racks toggle . 
The Visibility and Zones tabs are an efficient and very flexible means of navigating through a large mix.
The Rack makes setting up channel routing and effects a breeze.
Of course it needs key commands for the Agents etc, but to me the Mix Console is like the crown jewel of Cubase 7!
NIce job Steinberg!
