Which to download (tar.gz) or (zip)?

The Tarball (tar.bz/gz) is a Linux compressed archive, and all the files within are in the Linux formatting (UTF8 I think).
The Zipped version is for windows users who can use winzip or another archiving tool to extract the contents.

What's important here is that you have a decompression utility suitable for the file you download.
