Let me answer you this way....if ball hitches (including goosenecks) are superior, why aren't they used instead of 5th wheel (kingpin) hitches on Class 8 over-the-road tractor/trailers? Even those rigs towing double use pintle hitches to connect the dolly to the front trailer. As far as the implied integrity of the hitching arrangements, notice that safety chains are not required on kingpin-type hitches but are by some states on all ball hitches.
If you want to get into the design specifics, we can wade off into that discussion another time.

Safety chains are required on ball setups because there are more opportunities for error, not because they're inherently weaker. Wrong size ball or failure to lock the hitch and you could have an issue, whereas a kingpin is a kingpin and it locks in automatically.
I like a gooseneck ball on rough terrain. Nice and flexible and no issues hitching or unhitching at an angle. Not an issue in Texas where you can stand on a tuna can and see 20 miles, but it can be important out west. :B
Have you ever heard of a 5th wheel king pin crystallizing and failing?
Crystallized balls do happen!
However different strokes for different folks!
