The Rapid rung self stows and is always at the ready. Pull down, step up, forget it. There is no fighting it into and out of the bag, making it much more convenient to use, every time you want to take a dip.
The Rapid Rung has bigger diameter steps as well as wider steps giving your foot more purchase and making it possible to get two feet on a rung at a time. It also doesn't get twisted up, in fact it is designed to not be able to twist if it is under tension at all. It is also attached at two points instead of one making it super stable.
The self retracting rungs also make it less likely for a foot entrapment issue since there are no dangling open holes. In the rare event someone does slip off the grip tape and in between rungs while it is deployed, the thin 1/8" rope (2000# test) is able to be cut quickly in an emergency with your river knife. In the rare case the rope does have to get cut, I can replace the rope instead of buying a whole new ladder.
There are enough differences that it has a patent.
