I recently attended a Microsoft event “IT Camp: Virtualization” in Los Angeles where they distributed a product comparison white paper on VMware VShpere 5.5 and Hyper-V server 2012 R2. I was surprised to see how much the Microsoft Hyper-V platform has matured over the past few years and is now a viable option for virtualization in the Enterprise. Coupled with System Center Virtual Machine Manager 2012 R2, Microsoft Hyper-V will provide you with many on the features found in VMware.
