Whichever way you go, make sure either can be vented properly to the outdoors. Long vent runs and/or lots of elbows will reduce the amount of air that can be exhausted (possibly to the point of being useless).
Check the installation specifications for the ducting before making your purchase to ensure it can be installed adequately.
