High boy.....
I have heard all kinds of variants of High Boys. I had one guy try to tell me his Grandpa had a '84 F150 shortbox that was a factory highboy. 
I just changed the subject. It wasn't worth arguing over. Either way, I like the earlier ones better. Mostly for the brutish ruggedness. The ease of engine tranny swap prolly takes a close second.

One guy told me that the divorced cases also last longer because the are not bolted to the engine/tranny and the ride on rubber in a sense. This makes the truck has less vibration and the t case has more cushion because there is a drive shaft between it and the tranny. I still prefer a low boy over a high boy because of the stronger wider frame and wider rear leafs.

Greater reciprocating losses as well as a larger diameter connection between the case and the trans which may promote greater vibration.
Both direct mount and remote mount cases ride on rubber. In fact so does the trans and so does the engine.
Stronger frame and wider leafs make a truck more desirable? Perhaps in some applications, but for off road applications the narrow frame and narrow springs can maximize articulation. This flex can mean the difference between keeping a tire on the ground or not. Traction is sort of important.
Married cases have limited clearance so running a man sized u- joint is minimized as well as the over all travel due to the front driveline angle. The remote mount case does not have this problem. 1480 joints can clear without any trouble. Married (direct mount) cases might be limited to tiny 1350 joints.
Not so sure I am convinced that one has such a distinct advantage over the other.
