I chose Cyrus for the better shared folder system, so sales and accounts 
staff could have a shared folders for example. With Cyrus you have very 
fine grain access and permission control using the command line tool cyradm.

However one advantage of Courier over Cyrus is that Cyrus is not always 
easy to compile and install (though the O'Reilly book goes into some 
detail and a HowTo exists). The system I put together used Red Hat 7.0 
and Red Hat's Cyrus RPMS (and will very shortly, require updating).

Red Hat dropped Cyrus IMAP support after 7.0. Simon Matter is 
maintaining Cyrus IMAP RPMS at http://home.teleport.ch/simix/. He is no 
longer maintaining  Cyrus SASL V2 packages as these are now included in 
the standard distribution. Also the earlier Red Hat RPMS omitted Sieve, 
server side mail filtering.

 From what I have briefly seen, to upgrade a RedHat/Cyrus installation 
to Simons packages will not be entirely straight forward, but I might be 
wrong ;o)
