Rationale
To avoid post import cleanup like the following
https://www.redhat.com/archives/fedora-devel-list/2009-August/msg00563.html
I propose that we add a section to https://fedoraproject.org/wiki/Packaging/SourceURL that recommends packagers to pick the best source.
Use the Best Source
If we the upstream source archive is available in multiple formats, use the one that yields the smallest source rpm in order to save space on the mirrors and downloads of source RPM packages. xz/lzma compression (tar.xz or tar.lzma) is known to be the current best in terms of compressed size and time taken to decompress. The next best would be tarballs compressed with bz2 (tar.bz2). Otherwise pick gzipped tarballs (tar.gz) or zip compressed ones.
