As the name implies, both Obito and Madara are in their Ten-Tails Jinchuriki forms with Obito being in his controlled Sage Transformation and both having ten Truthseeker Orbs. Obito has one Sharingan and one Rinnegan. He can use all of the Six Paths of Pain including the Outer Path. However, he cannot use corpses for these techniques. Also, Obito cannot use Kamui with his right Sharingan. He can also use manifest Tailed Beast Mode outside of his body. Obito is banned from using the Limited Tsukuyomi from Road to Ninja considering it is movie- only. Madara only has one Rinnegan and he cannot use Sharingan abilities like Susano'o and does not have Rinne Sharingan. Also, I probably don't need to add this but Madara can only have one Limbo Hengoku clone.
Also, no one-shots (ex. Madara using Infinite Tsukuyomi to put Obito in a dream and then killing him in his sleep).
EDIT: No databook stats or statements made by characters. However, light speculation can be made but all statements made on this debate should mostly be proven by actual feats made by a character.
