Hyper-V in Windows 2012R2 vs Windows 2012

I have a Hyper-V running on Windows 2012 Standard on current server and I am getting a new server hardware.
I like to install Windows 2016, but I am not sure when it will be released and can't wait for that.
So alternative is getting Windows 2012 R2.
Is there enough benefits to purchase Windwos 2012 R2 in terms of Hyper-V?
If there is no substantial benefits, then I will just use Windows 2012 because  OS and its user licenses have been paid for and maybe upgrade to Windows 2016 when it becomes available.

Take a look here for a breakdown of the differences.

@DLeaver,
 
 I read that article before posting this question.
 I was hoping to hear from those who actually managed Hyper-V  in both Windows 2012 and R2.

Let me add this to my original posting.
This site with Hyper-V on Windows 2012 has 3 Virtual Machines with about 10 workstation PCs.
Three VMs are SBS2011/DC, One Terminal Server and Windows 7.
There will be no additional Hyper-V servers in the future either. It is a small network.
Ok....slightly frosty response to someone who is trying to assist you...

I have managed both, but your original question does not specify what it is in particular you are hoping to achieve and what extra benefits you are hoping to see from an upgrade.

Your last post lists out an infrastructure - again there is no specification regarding what you are looking to achieve or what the infrastructure currently lacks that you are hoping a newer version of Hyper-V will provide.

I supplied the link for you to see what the differences are under the assumption it might answer what you were looking for.

Bear in mind that people who contribute on here do so in their own time - you have a number of solves under your belt so I know you can appreciate this.  

To be blunt, if you want a more detailed answer with specifics then you need to better qualify your requirements in your question.

I am now going to un-follow this question

Please accept my apology. I did not meant to upset you.
Maybe I was not clear in my original posting.
But the below is more like what I was hoping from experts if the question was "Benefit of using Windows 10 over Windows 7".

1. Windows 10 is faster than Windows 7.
2. Windows 10 brought back Start button that disappeared with Windows 8 while maintaining "tile mode" introduced in Windows 8.
3. Better graphics

Thanks for sharing your opinion.
Why is this even a question - install Hyper-V Server 2012 R2.  It's free.  No licensing costs.  Then you get the features.  The improved replication time is useful when setting up off-site disaster recover - and the ability to do off-site AND a local replica also improves disaster recovery.  And, did I mention, it's free?

I purchased Windows 2012 Server standard and User CAL. What do you mean by "Free"?

What is the difference between installing Windows 2012 Server and install Hyper-V (& create VMs) and installing this "Free" Hyper-V Server 2012 R2 (& create VMs)?
Basically - GUI.  There is no Graphical User interface on the free one.  But you can use the free version of 5Nine Manager - that installs fine.  And you can also manage from Windows 8 or later systems using the Hyper-V MAnager on those.

I got you. I did not even know there was free version without GUI. Thanks for the information.

Update:

@DLeaver
"Personally, as an OS Server 2012 R2 feels like a more complete and stable OS in comparison to 2012." --->
I went with 2012 R2/Hyper-V on HP Proliant ML110 G9 Server, 56GB RAM, 600GB 15k 12Gbps SAS hot-swap HDs on RAID 10, HP Smart Array P440/2 GB RAID controller. I feel like 2012R2 feels like a more complete and stable OS.
This server screams when it boots up and when it runs VMs.
Thanks for the update

That is fairly typical of the ML110 (most HP hardware come to think of it!) - they normally calm down after the initial boot.  Sounds like the VM's are pushing it hard at times also...

maybe I misspoke.
This brand new  HP ML110 G9 server runs so fast that I am just thrilled.
The best server that I have ever built. SBS2011 VM and Windows 2012R2 VM run so FAST!
My older server with Windows 2012 had slower SATA 7200 rpm HDs and Slower CPU on Intel Board. The same VMs had so many problems - BSOD, lock-up, freezes ... etc.
Now with W2012R2 on HP ML110 G9 server, it is like heaven!
Ha ha, thats good - yes HP servers run well, just start up like a jet engine taking off!

Glad its all working for you :-)
