RGN vs folding gooseneck buying used trailer for track hoe

I need a trailer to haul my Deere 200D hoe. I have been looking at rgn trailers and have ran across a good looking Load King folding gooseneck. It is a hydraulic fold. I have no experience with folding gooseneck trailers (and not much with removable gooseneck).

What are the advantages and differences of a folding gooseneck vs. a removable gooseneck?
