I'm thinking - guessing, really - that the length of a TA being physically limited while the side view distance from the axle to the virtual intersection point of the LCAs and a UCA is not has something to do with it. Maybe rigidly fixing the diff with respect to the TA inclination is a disadvantage.

Oddly enough, you'd start your TA geometry plot by assuming that a virtual 3rd link exists at the chassis end of the TA. This fictitious link will be perpendicular to a construction line drawn through the TA's chassis pivot and the axle center (this construction line will lie close to, but generally won't be coincident with, the TA's long axis).

The TA has a solid anti squat characteristic, while accelerating. I can see this advantage in reverse during braking. Since I more into accelerating, it is clear to me that I like the TA. I can see the 3 link is more of a neutral design..
