OK, I was exaggerating (notice the smiley).  But I do have a feeling
(and just a feeling, no hard data), that ntfs-3g is making the
in-kernel ntfs filesystem increasingly irrelevant.  And yes, that's
mostly because of the features, but also because the performance is
not at all as bad, as some people would think a userspace filesystem
has to be.
