I haven't used both per se, but I've experienced similar types of each in 
various RVs. Propex is forced air, and the plat cat is a radiant type 
heater. Radiant uses less electricity, having only a small fan feeding 
combustion air and venting exhaust. Forced air will heat the whole interior 
fairly evenly, but you can warm your hands easier in front of a radiant 
heater. Forced air you can squirrel away under the rear seat with only a 
warm air vent showing, while radiant you'll have to find a sizable exposed 
surface to mount it (back side of the pass. seat pedestal in a Vanagon is 
pretty much your only reasonable choice). I prefer the propex design, 
personally, but I've always benn weird about exposed radiant heaters.
