I can't comment this since I used only Linux in all my life, hereby
unfortunately I can reasonable compare the still unoptimized NTFS-3G
driver only with the Linux file systems.

On the other hand, some users are indeed reporting that the driver is
faster in some scenarios than the Microsoft one. This may also explain why
we get a few technical questions from file system developers working for
Microsoft.

Well, the random file creation part is the most meaningless and misleading
part of the microbencmark, i.e. not real life usage. If you make your own
tests (no need for Windows: http://ntfs-3g.org/quality.html#howtotest) then
you should find that the difference is far not as big during normal usage.

There are many reasons but typically it's interoperability. Hundreds of
million computer users are "stuck" to Windows for whatever reasons. I think
they should be given the chance to decide what works the best for them.
