Just went through the same thing as we just purchased our first 5th. Actually delayed our tacking the 5th home by 4 days because by the time I decided on the hitch, and they order it I had to wait for the delivery and install. Seems like picking the hitch was the hardest part of the whole deal.
Anyway, we decided on the Pull-rite over the choices you have listed, I looked at all of those plus the Hensley, it actually came down to Pull-rite and Hensley when I could not get a local dealer for Hensley I went Pull-rite.
Relevant or not I wanted a system that has a single wrap closure around the pin, just felt better visually to me when I check that I hitched it correct, I also wanted a system with a under-bed system so that my truck bed could be clear when I did not have the hitch in it and wanted to haul something.
Also our 5th has a GVWR over 14000, but I decided that at the cost of a hitch I'd rather match it to the truck than the trailer so I purchased a 20.5K Pull-rite super 5. You should consider this as well unless you never plan upgrading campers.
