Hyper-V Review
Hyper-V 2012 R2 vs. VMware vSphere 5.5

I was won with Hyper-V 2012R2 recently and the table below based on customer RFP (edited). This articles all about technical, there is not related with TCO/ROI, licensing cost, “political”, etc. Another to noted is the Windows Server 2012 licenses is based on 2 socket CPU, meanwhile VMware vSphere is based on 1 socket CPU. With Windows 2012R2 Datacenter, you will eligible to have unlimited Guest OS licenses.

Also System Center 2012R2 licenses based on 2 socket CPU.

Enjoy it, and let me know if I missed something or need some updated.
