depends...what will you use it for?
unless there are application limitations on the OS requirements or something else in your environment, go with 2012 R2

I think you should tall to your client and understand *why* they want 2008 R2. Otherwise it is just a matter of "everybody has an opinion" with no justified reasoning to choose your opinion or theirs. So.....sell them windows 98.

There could be many reasons as to why they may need 2008 (i.e. application, CALs, skill set, etc.).  If your client has Volume License Agreement with MS then buy 2012 R2 and you could legally downgrade it.  Otherwise it is always a good idea to get the latest version, however, ensure that you have all the required CALs, etc.
Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

She was told 2008r2 was solid at a friend's company and that the other company bought 2012r2 servers, three of them, and had slow transfer rates. Downgraded to 2008r2 and transfer rates were normal. She hears this info and has a fear of 2012r2...

The server will be a file sharing server and will host some vms.

I have read about similar issues. So far, windows 2012 or 2012r2 are rock solid!!

The VM can be whatever OS they want.  The bare-metal install should be 2012 R2.  Review the capabilities of Hyper-V and it's evolution from 2008 R2 through 2012 R2 - the enhancements and capabilities (Replica for one MAJOR reason) demand using 2012 at least).  At an absolute MINIMUM, make sure you buy a 2012 R2 Volume LIcense and you can downgrade to whatever you want and get 2 VM licenses for Windows Server.
Lee W, MVPTechnology and Business Process AdvisorCommented:
BTW, DO NOT make the bare metal system your file server - the bare metal system should ONLY be your hyper-V server.

Also, there can absolutely be logical reasons to use older versions of server but you should discuss with the client and TEST/communicate with Software Vendors to ensure whatever version you want to use is appropriate and will continue to be appropriate.
Here is my 2 cents:

Some IT companies/guys make what is to me a non-sense use of virtual machines.  Some will say, "the processor is doing nothing on a file server machine, it can be doing something else".  Meaning some IT people like to have their servers using about 80 to 90 percent of their processors all the time.  Me I do like VM's but I will build them properly and with enough resources to avoid slow response and unwanted angry users around the office complaining about how slow the system is.

Now, if there is no SQL or any other platform not tested on 2012 a good planned server infrastructure should be good regardless the server's OS.  Try to explain her... You can have an F1 on the street but that doesn't mean you can achieve full speed in the freeway at rush hour and also the opposite, you can have ford fiesta on a race track but it can go faster as an F1 will.

So, everything in the organization should be taken on consideration to get the end result expected... putting everything on the server is not quite the only thing to consider.
