Geometrically they should articulate the same, but in practice there is more friction with the T setup, because strain on the wrapped sheetmetal outer element tends to squeeze it onto the fixed pin of the T, and because a wrapped element is not as geometrically perfect as a machined hole.
It doesn't help that the pin in the T setup is more exposed to salt
aggregating, and there is twice the projected area under load.
According to classical friction theory, this extra area cancels out and does not give rise to extra resistance to articulation, due to lower contact pressure
But in practice, with rough surfaces or particulates present, the theory no longer holds.
The other factor is the severe stress concentration arising from the 'armpits' under the T setup's crossbar. Added to that is the severe coldworking implied in producing them, which sets stainless up to fail.
So it makes sense to me that, as neilpryde claims, the T toggles would crack more readily than the eye toggles.
