I'd prefer Windows as that is what we run it on .. currently Server 2003 R2 x64, but the training should probably use Server 2008 R2 (x64) as 2003 is heading for EOL/EOS and 2008 has been around for at least 3 years now.
I would personally prefer to be running it on Linux, but that is out of my control. :-(
