The relay switching matrix is arranged differently, so one or the 
other might be more convenient for how you want to wire things 
up.  For instance, the RCS-8V is basically configured at 5 relays in 
a star around a common point.  You can set the relays in the RCS-8V 
up so that they are either open or grounded when the coil isn't energized.

The RCS8V uses rivets to connect the SO-239 connector grounds, and on 
my switches, some of the rivets aren't all that well installed 
(partially off the hole, for instance).  Probably good enough, but if 
you're a perfectionist, you'll be unhappy.

Look at the relay configurations and decide if it does what you want 
(in terms of isolation between ports and grounding of unused ports).
