Actually, the title of this posting is bit inaccurate… There is no vs. when it comes to operating systems. All there is is an and!
Almost every day I run into people who are… narrow-minded, for the lack of a better word.
Narrow-minded, because they approach the whole thing backwards. They first set their mind on a specific OS, and then they look at what the options are to deal with the project at hand.

If this is not the case, then and only then, you can start making operating system choices.
And don’t worry about ending up with a mixed environment. I know from long experience that in quite some cases Microsoft & Linux talk better together than Microsoft & Microsoft, or Linux & Linux for that matter.
