What is the difference between \vspace{\fill} and \vfill? What about the starred version of them?
\vspace{\fill} and \vfill are not exactly equivalent. They are if they appear between paragraphs, but not if they appear in a paragraph.
\vspace{\fill}in a paragraph will add the filling vertical space below the line in which it eventually appears;\vfillends the paragraph at the spot and adds the filling vertical space.
Indeed \vfill is a TeX primitive, while \vspace is defined by LaTeX to have the described effect when found in a paragraph. In vertical mode, \vspace{<glue>} is equivalent to the primitive \vskip<glue>. See \vspace vs. \vskip for more information.
There is no \vfill*, if you're asking about this. The difference between \vspace{<glue>} and \vspace*{<glue>} is that the latter is not discarded at page breaks. See Question about spacing \hspace and \vspace.

2I didn't know there is no
\vfill*, but I was also interested about\vspace*{\vfill}– Mario S. E. Jun 12 '13 at 11:02 -
3@MarioS.E. You probably mean
\vspace*{\fill}: it exists and has a similar behaviour to\vspace*, only using\fillas the length for the vertical space. One of the uses is to put a paragraph at the bottom of the page, e.g. a colophon, when there is no other text on the page (hence the use of the*). – tricasse Mar 21 '15 at 15:05
