That depends on your definition of "efficiency", but for most reasonable
definitions I can think of, I think you have it backwards.  

For example, with Freenet, when you publish content, you only need to
upload the file you want to publish once (together with some check
blocks for FEC).  With BitTorrent, you must distribute it from a central
server, and it might be downloaded many times over from that server
until there are enough people out there sharing the file.  In most
cases, BitTorrent will require orders of magnitude more of the
publisher's upstream bandwidth than Freenet would.

Personally, I don't find BitTorrent to be a particularly interesting
technology.  It is even more centralized than Napster, offers no
anonymity, and publishers must set up and run BitTorrent trackers for
the entire duration of their content's availability.
