Juubito > Juudara (Theory + Evidence)

Madara > Obito ... /thread.

It hasn't been confirmed that son > moon, as that would mean that Naruto/Ashura is/was stronger than Sasuke/Indra.

On top of that, Madara has a more stabilized jin form.

Exactly. Juubito has the Sun (and more Chakra than Juudara), while Juudara has the moon.

The only reason Madara is stronger than Obito is that Obito needed to be nerfed when he got Juubi. Kamui Juubito > World.
