I just tried again, this time disabling all compression on my side.

Checking on the USRSTATS of the BBS I called I see
 
Protocol              LAPM 244/6
 
The V.42bis values came from the Couriers end,  strange values.
 
The Courier is certainly claiming to support only 244 octet frames,
not 256 octets like every other modem I've tried,  and the Courier fans
are saying.
 
What are the Couriers saying when they connect?  Saying 256?

Without a doubt the Netcomms give a noticeble performace increase.  If you
only limited yourself to tansfering incompressible data like Bill then
there may not be much difference.  I use my modem for UUCP, PPP,  dialing
unix hosts,  and of course BBSing.  I do notice the difference.
