I’ve had three gooseneck trailers (including currently), an American bumper pull, and a Brenderup. I prefer the GNS, although the Brenderup - which I usually towed with a V6 powered SUV - was a far superior towing experience to American BP trailers, I’ve also towed a few friends’ American BPs, in addition to my own.
I towed my not-heavy American BP with both our Cummins and the SUV (which it was rated for), but still preferred the Brenderup, even to the Cummins towing the American BP. The inertia brakes are wonderful, and it cornered as though it was on rails.
However, when I required another tow vehicle, I went back to a full-size V8 truck – influenced by the significantly higher price of a suitable replacement SUV* – and I decided that I might as well go back to a GN trailer, too. Sold my Brenderup to a good friend, who tows it with a Volkswagen SUV. If I was ever again in a situation where my tow vehicle needed to be a SUV, I’d definitely consider another European trailer, especially if I was doing anything more than occasional towing to a nearby location via surface roads (not interstates), such as a vet clinic or lesson.
No contest that a GN is far superior, IMO, in regards to being affected by the double-bottomed semi tractor-trailers blowing past on the highway, especially to the American BP. The Brenderup did okay in that type of situation, although not as good as a GN. I do know that a GN is back there, but the tail is not wagging the dog.
*I live in the land of pickup trucks, so there are generally deals to be had, as compared to comparable SUVs
