It depends on whose religion you believe in more strongly :-)

Rich Salz:
They are targeted for different environments, although both systems seem
to work fairly well outside of their targets.

INN is designed for hosts on the Internet with a fair amount of memory and
multiple fast incoming NNTP feeds.  It's a full USENET system, but most
traffic is NNTP.  (E.g., rnews unpacks a batch and sends it to the server
via NNTP.)  If you do NNTP, you'll find it easier to maintain the one
single system, rather than two.  Also, posting is synchronous -- when
inews returns, the article has been written to disk and queued for
forwarding.  [By comparison, C News is asynchronous -- Mark.]  INN puts
a low, constant, load on your machine.

Several people run INN on UUCP-only machines.

David Myers:
Whether or not you use NNTP may influence your decision.  If you wish to
use NNTP internally, then with C News you have to also install the standard
NNTP package.  [Don't confuse this package, named "nntp", with the NNTP
protocol itself!  It's just one implementation -- Mark.]  This may or may
N, you get
it all in one package.

Geoff Collyer:
This should cease to be an issue once we ship the Cleanup Release, which
will contain an NNTP implementation.
