He was talking about JJ Madara, because in that form he would be complete (considering that he has the closest chakra to Hagoromoo at that point)
Even a Obito couldn't implant double rinnegans and become juubi jinchuuriki, it gave too much power to handle.
Now you shouldn't compare Obito to Itachi, he would easily pawnge him...
Let the movie stay as a movie...
Now if you want to know the level of strengths between the two it is this:
Ms Obito = alive blind sm Madara
Rinnegan Obito is right below Rinnegan Madara
Rikudou Obito is right below Rinnegan Madara/Both eyes included
DMS Obito is either greater or equal to double rinnegan Obito no juubi jinchuuriki for the both
I have explanations on why
