PyPI vs RubyGems
No leader: the top candidate RubyGems has only 0.31 confidence (low), below the 0.35 needed to declare a winner. The attribute-by-attribute breakdown below, with a source and date on every value, is the honest way to compare them.

RubyGems
RubyGems is an open-source package hosting and distribution platform where Ruby developers discover, install, and publish gems (libraries). As a free, community-maintained service, it processes billions of downloads and is central to the Ruby development ecosystem.
