The B&W turnover ball system would be my choice, if actually using the ball for a heavy gooseneck trailer.
If you just want to fasten an aluminum tubular hitch to it, any of the ball systems above will be solid enough.
I know you dislike/don't want rails. They are a much more solid attachment, than any single point hitch. You would have many more options for a hitch, and if you want an Andersen hitch, the steel one that Cummins 2014 has, is a more solid version.

I installed rails and use the steel Anderson hitch and it's a great combo. My father in law hasn't had any issues with his gooseneck model, though. I wouldn't have a problem using either setup. I kind of like the ball style hitch better than the standard fifth wheel setup. I also have a plate I can drop in my rails for standard gooseneck trailers and it works well too.
