Not sure of the terminology of the systems you mention. We have gas-fired, hot water baseboard heat with a separate central AC system. Must say, I'm very happy with it. We looked at the wall/ceiling mounted separate systems prior to doing the central at the time (@ 15 yrs ago) and decided it was worth the extra $$ (and not by much) to go the route we did. Have AC in every room except dining room. Works well for us and seems to be quite efficient.
