In this case best means a format understood by the
majority.
Jsut becasue something is popular doesn't mean it's well understood. I'll
bet most people who use Winzip or whatever haven't a clue as to what a
zip file actually consists of.
In the future ZIP formats will be better understood than any other current
format for the simple reason there are more zip files to examine than any
other.
But I'll bet now that more people understand the internals of linux than
understand the internals of Windows, because the former is 'open' and
documented, the latter isn't. Even though there are many more Windows
machines than linux machines :-(
