"gz" is a suffix, "bzip2" is the name of the program that
does the compression and "zip" is both the suffix and the
program.  First and foremost I would recommend being
consistent.  :-)  No matter what you choose, you still
need to have both be specifiable so you are not boxed into
cutting a new release in order to support a combination
you didn't plan for.

An amusing exercise for the reader:
add "rpm" and "pkg" formats  :-)
