Years ago I compared sizes of compressed files in /usr/share/doc using
different compression methods too, possibly restricting to specific file
types (for example changelog and copyright).

IIRC bzip2 had a better compression.  Compressing dpkg's changelog on
stable seems confirm this:

    $ zcat /usr/share/doc/dpkg/changelog.gz | bzip2 | wc -c
    145586
    $ zcat /usr/share/doc/dpkg/changelog.gz | xz | wc -c
    167844
