Assuming .bz2 and bzip2 format are the same.
I did following test.
Downloaded
http://umn.dl.sourceforge.net/sourceforge/gaim/gaim-0.67.tar.bz2
(mirrors at http://prdownloads.sourceforge.net/gaim/gaim-0.67.tar.bz2?download )
unzipped and re-zipped 7-Zip format.
and here are the numbers
gaim-0.67.tar.bz2 - 2.79 MB ( 2,934,003 bytes )
gaim-0.67.tar - 15.0 MB ( 15,728,640 bytes )
gaim-0.67.7z - 2.10 MB ( 2,210,044 bytes ) 24.67 % more than bz2
When I compare zip & 7z format I get average of 25% advantage.
So bzip2 being a better format 24.67 % should be little high
