Sure.

As Eli said, just stat find is faster than, e.g., "bzr ls" on my
GNU/Linux system doesn't mean much. One benefit is that if you have a
bzr project, you'll have bzr installed. That doesn't need to be the
case for find at least on Windows systems.

Hm, git can list untracked files, list ignored files, and also get a
custom ignore pattern.
"bzr ls" has an --unknown flag which should list unknown files and an
--ignored flag to list ignored files, but in my version it then just
lists nothing when I specify either one.
"hg files" doesn't seem to have a way to list untracked files. Same for
subversion.

If you have an interface in mind (i.e., list-files all arguments and
their meaning), I can try and check how far we can get.
