The general consensus has been that a vented is better, and faster to dry. (disclaimer, mine is vented). The non vented heats the clothes to turn the water to steam, then uses cold water to condense that steam to water, and drain that condensed water (along with the cold water) to your sewer (which may be to the grey tank or directly to the sewer outlet). Not only does it take longer, but it also uses a lot more water for that process. And some who have the non vented say the clothes still come out feeling somewhat damp. BUT, there are some who have said they were satisfied with the results.

The con of the vented is that you must cut a fairly large hole in the wall for the vent. But many here have done just that.
