Huh? PDF supports G4 fax compression and the newer JBIG compression
algorithms, which until very recently (with the advent of JBIG2) were
the to highest-compression lossless bilevel algorithms publicly available.
I stick to G4 because it's not encumbered by patents, but JBIG can
compress about 5-10% better.
For continuous-tone images, PDF supports JPEG compression and a few other
types.
What formats are you claiming have better compression than PDF?

DjVu has a hugely more efficient scheme for their files, DjVu files of the
same document are a fraction of the size of PDF's.
I don't want to switch to DjVu, partly of the legal tug of war going on with
it, partly because I already bought Adobes Acrobat, partly over the fact it
would confuse too many users unfamiliar with it.
