False on several occasions. To preempt on what your belief is based; you can't take an Obito into consideration, who started doubting his actions in the very last moment after several Talk no Jutsus of both Madara and Naruto, and his personal connections with latter. If not for that reason, Obito would have shattered them in that moment. They didn't stand a chance against him until this moment.
There are so many things Obito can do with them, while Senjutsu is in fact the only way to do something against his absolute defense, and yet is not a guarantee to handle him, as proven by him when defending himself against the with Senchakra enhanced attacks of BM Naruto and Sasuke's legged Susanoo, who got helplessly foderrized by him.
They would already fail before the Musekiyōjin, which was made to cage the alliance an tanked four Juubidamas effortlessly. From there on, Juubito will make use of his most powerful moves to trash them. Whether it is growing tendrils from inside the barrier to shot multiple Juubidamas in all directions, shot spheres of Omnyoton who possess a destructive radius similar to a Bijuu's Bijuudama or release the Shinju, which will immediately suck up their whole Chakra. When I talk about Obito's barrier, Madara's Shinra Tensei, no matter of how powerful it might be, will repel those Juubidamas but will never let them leave the barrier they were caged in. No matter of which scenarios you would consider happen, creating such a barrier will be always a safe step to Obito's win.
And even if Madara and Naruto were durable enough to survive a longer fight with Obito, latter is still in the position to activate Mugen Tsukuyomi, making it a countdown of 15 minutes until his autowin.
And even apart from the barrier, Juubidamas, Omnyoton and Shinsuu, Obito is in possession of Rikudo Sennin's Double-Helix-sword, which was hyped to be the item with which the world was "created", regressively able to destroy it. Obito claimed that this sword would lead to his absolute win, if not for his disbelief in that very last moment.
As for now, they both didn't show the power to even argue their win. A number of clones who use Susanoo and are enhanced with Kyuubi's Chakra, and not even the Rinnegan or perfect Susanoo (his so called strongest technique) will safe them from what Obito can do with them.
