this style of hitch has been around for quite awhile... I can see no advantage to it over a standard gooseneck hitch, as you still have to raise the jacks quite high to connect/disconnect from it...
it is no more secure than a gooseneck or 5th wheel hitch, and with it being more akin to a gooseneck hitch, the disadvantage comes with the amount of space that the hitch takes up in the bed of tow vehicle.... so if the footprint of the hitch in the bed is ok, its my opinion that it would be better to just use a 5th wheel hitch so that you can easily connect and disconnect with the least amount of effort....
