Sometime on Jan 16, Trevor Warren assembled some asciibets to say:

It doesn't matter. on linux, both zip and tar/gzip work. on windows,
Winzip can handle zip as well as .tar.gz files.
besides, tar-gzip gives better compression than just zipping.
No, it has nothing to do with the algorithms used, just the order.
zip does a compress first, concat second, tar | gzip does the tar -
concat first, and compress second.
doing the concatenation first increases the entropy in the file, making
it a better compressible.
compression is an entropy reducing process (and as such contributes to
the longevity of the universe), and therefore, the more entropy present
initially, the better the compression.
