The answer of course is that the symbolic link stops working when you
move the file it is pointing to, whereas the alias does not.

Hard links, like aliases, do not break when you move the file they point
to - but then hard links can't traverse file system boundaries.

I don't use aliases, but apparently they can even point to a file stored
inside a disk image. When accessing such an alias the system will
automatically mount the disk image.
