I know there’s a few other more recent inventions out there like the “lock n roll” coupler but I’m only interested in comparing the +/- of the various Bantam trailer couplers.
There are certain reasons why I prefer the ball hitch and other reasons why reasons why I prefer the pintle hitch.

Ball coupler  +/-
No play in coupler should provide more precise maneuvering.
Quieter operation especially when off-road.
Fits direct to Willys draw bar.
The coupler pivot point is further back from the rear axle so is that good or bad ?

Pintle hitch +/- 
Purportedly this design allows more sideways articulation than a ball type coupler ? How much more ?
Is the increased angle of approach/departure really that much more helpful when maneuvering off road ? 
The pintle itself fits direct to the frame and the coupler pivot point closer to the rear axle; so is that good or bad ?
Looks to me like the common military pintle will contact the tailgate preventing it from dropping down level. Do some pintles set a little lower than others?
Lunette design is less likely for trailer thieves to hook up ?

Here is the pintle I have:

Ken,

Obviously WWII jeeps did not have tailgates so this would not have been a problem back then. Nor did M38A1s with M100s or M151s with M416s.

Having been in a Tactical Comm Unit for 40 years now and having towed many trailers with the pintle hitch it does seem to conform to very good articulation in severe offroad conditions and is probably why all the mil vehicles used this style hitch.

The M151s are what we had when I first joined with a matching 416 trailer looked like this but the MEP-016 generator was mounted in the trailer.




Here is a good example of how good the pintle hitch is...one of ours hit a patch of black ice on the way out of base for a mission. We rolled a few but the MRC-108 radio pallet in the rear acted as a roll bar and kept anyone from serious injury.


They are little tough to back up with such a short trailer with or without the pintle vs standard coupler.

...and I will bet that the pintle and the lunette were still connected!

Yes, we never had a pintle failure and they are always safety pinned too.

I can say many trailer tongues were bent on M720 mobilizer dollys from backing with duces - this is a big no-no. We had to unhitch and hand roll these any time backing was involved.

Interesting Art. 
I’m pretty sure the pintle I posted was off an M151.
Casting #7073213
If it was about 1/2” lower then my tailgate would drop all the way down.
Wanna get a Bantam someway/someday but not sure what hitch I prefer.
I imagine the rare optional civvy pintle is a tad lower.

To use the pintle hook on a CJ you lower the hook by mounting the top pintle mounting holes in the bottom holes on the frame and drill two new lower holes in the drawbar.

I stole this from another thread on installing a receiver hitch but it shows the pintle in the bottom two holes then redrilling the lower holes:

Now why didn’t I think of that ?
Just relocate the pintle down an inch or more and I can still retain the draw bar too.
I see what looks to be a piece of radiator hose inside the lunette ring. That’s a great idea too.

Good eye...I didn't catch that at first.

Eliminate the clunks and save the paint too.

I got to looking at several of my cj3 frames and realized that about half of them already have the 2 extra low pintle holes that were punched at the factory.
