I learned to drive on a gooseneck, but I bought a bumper pull... mine is a brenderup. It is as stable as you could possibly dream of being. It pulls/handles/maneuvers Way better than that dang gooseneck. (you have to take turns SO wide with gn and be so much more aware of every inch) Backing can be a little tricky with bp... but I never did learn to back that gn either, so. I would rather have my bp any day
I also find it a much bigger pain to hook and unhook a gn than a bp. Don't forget to drop the tailgate when you pull away!!
But depends on how you want to use it.
Like someone said, if you have a short bed truck, not very good idea to have a gn. I've heard people do serious damage to their trucks pulling a gn with a short bed.
A truck can generally
can carry more weight with a gn as the weight on the truck is distributed differently. Gn's have more room and you can use upper part for sleeping.
But your storage space in the bed of your truck is reduced.
I have a cart, so I need the bed of my truck to throw my cart in.
Bp are smaller and store better. They fit into tighter spots (I guess depending on the trailer in question, but) good for small camp grounds or crowded trail heads.
