I have the Andersen gooseneck mount. It's my first FW hitch, so consider my response based on that.
I chose the Andersen because:
1. I already have and use a B&W Turnover Gooseneck Hitch
2. I routinely use the bed of my truck for general hauling so I need a flat floor.
3. I liked the light weight
4. Though you'll find critics online, you seldom find someone who owns or has owned one complaining about them.
What I've found is that is amazingly easy to hitch and unhitch, tows nicely and is very convenient going in and out of the bed. I can turn 90 degrees in my short bed Ford. I simply can't come up with a reason to even consider another hitch.
YMMV
