The major difference between Deckadence and other vinyl pool mats is that there is a silicon (nonskid, as you put silicon mats under carpets) backing. The other vinyl mats are otherwise relataively similar. If petrochemicals, such as gasoline or oil gets on the Deckadence, it becames very hard and stiff.
I don't put the mats in a commercial Washer. No need. I just lay them on a concrete pad, turn the hose on them, and if necessary use a soft scrub brush (standing up type, long handle).
They might be slightly softer.
I had both types: the Deckadence because it came in wider width for the cockpit and the vinyl loop pool mat (cheaper kind) in the cabin where narrower width works well. The material does not "skid" on the floor where it is confined, so the non skid backing is not necessary. I had pieces cut for under the table, under helms man's feet, in the head the cabin step (industerial velcro there), I would not trust either type on that small step without being secured.
Is the Deckadence slightly better? It is a little softer and has the backing. Otherwise either is comfortable under the feet.
My only motivation in recommending the plain vinyl pool mat, is to save the boat owner a few bucks. I had a chance to evaluate them both over a number of years to use them on the same boat.
