I have no references to back me up (although I did formally study the
Burrows-Wheeler transform a few years ago) but I believe the block nature
of bzip2 allows you to recover parts of files beyond failures. Gzip
compression is based on the context (part before) so if you lose that, you
lose everything after that too. There is a patch for gzip that adds
'blocks' (basically 'restart' points) to provide better reliability but
I'm not sure if it's part of gzip proper yet.

Again, I don't have any references to back me up, but if this were a
real-time quiz, that would be my answer :)
