I can't speak for everyone but in my experience it was like going from riding in my old Jeep Cherokee (which had rear leaf springs) to any car with a modern independent suspension - just much more comfortable, less bounce, less sway. I'm sure someone can give a better explanation than I but I think it's similar to the difference between a solid axle vs. independent suspension in a car, meaning a wheel can go up and down on it's own with out affecting what the wheel on the opposite side is doing where as with a solid axle & leaf springs if one wheel goes up, the opposite wheel wants to go down and then the rocking ensues from there (only without the benefit of shock absorbers in teh case of a trailer.
