Depending on the hitch rating a gooseneck can generally tow more (when talking about the tow rating of the vehicle hitch) nowadays some of the trucks have a class V 2-1/2" reciever and that can negate this but a few years ago tow ratings between traditional hitch vs goose, the goose was always higher rated. The turning radius of the goose is far superior.
That said a goose will be heavier and take up a bit more room. They make 3point goose adapters for your 3 point so you can move them either way with your tractor. Not sure the weight rating on them though.
As far as brand this seems to differ greatly by location. Always get a little extra if you can. I'm not a huge fan of dumps for soil/stone/rock (it's amazing how heavy this material is and how little you can actually move at one time), yes they work but for the time and effort you can usually get a local dump truck to handle it for less. Now if you have the time and just like having and using equipment they sure are awesome.
Buy the biggest axles you can swing, make sure they are an easy lube style.
Check what coating/paint they use and warranty.
Check the tires and make sure they are quality (a big cost cutter on the cheaper versions)
Check the thickness of the deck and frame members
I'm a fan of power down models, some are gravity and that can be a pain.
Type of cylinder scissor vs dual
Gate type (3 way spreader, simple swing, etc)
Ramps and equipment package?
I can tell you if you get ramps I'd shoot for some that store to the rear under the trailer. Mine are high mounted on the sides and while I've always been strong and in shape I absolutely cannot stand using the ramps.
Anyway just a few thoughts, I'm sure you had considered them. Best of luck, Rye.
