Best durability among these 5

[Uchihakil]

It was never stated that TSB's durability is dependent on how much chakra you put into it but maybe.

The juubi is nature itself I doubt it won't use nature energy, maybe omyoutun adds more defence on top of it negating non senjutsu techniques, and juubito did'nt apply it
On topic
Tsb/juubi (the juubi tanked an explosion inside its body, I think it can tank those 4 juubidamas)
SS (tanked 11 bijuu damas from full kurama embedded with PS sword)
And ofcourse narutos kurama avatar = sasukes PS

TSB
Juubi
The rest not matter
