Perfect Susanoo is not doing anything against Tobi ...the Juubi in larval stage was several times stronger than the Kyuubi that is nearly on par with Madara's PS...in bulk form far above ...and it's Jinchuuriki is noted to be stronger...PS' spotlight is over now ...it is outclassed by Shinsuusenju in even defence considering it could withstand Renzoku Bijuudamas with cutting edges before exploding ...so If Madara is claimed to be stronger than Hashirama now ...he has to show something of a much higher calibre than this ( PS ) ...then if you saw Naruto and Sasuke's kyuusanoo land a hit on Juubito is because he had to be defeated in some way ...If he hadn't lost himself in his thoughts he would have easily won...and he always talks shit when confronted by Naruto because their ideals once opposed themselves ...he's up against Madara who had the same as him. Remember the thread opener gave Tobi the rinnegan here...Perfect susanoo will be absorbed right away...If you say so ...Madara even hoped Obito who was still in his 1st Jinchuuriki form at that time...hoped that he didn't notice him...seriously myself,If I was not afraid of someone ...I would have never said such a thing ...you must really be afraid to say so...and also I can see Rinbo : Hengoku hitting Juubito because it seems to be an unexpected attack and Madara can focus it on any of Obito's parts of his body that isn't covered by onmyoudon ...nevertheless I can't see him hitting him in any other way and I can't see him hitting Juubito twice as he'll be aware of it and will be more cautious next time...though I can see Juubito countering a slash from PS.
Edit - There's a possibility that Madara can repel Onmyoudon with a senjutsu-empowered Shinra tensei ...but in the face of a large number of Point-blank range Bijuu Bombs ...he'll shit in his pants and it's nearly impossible ...he may repel them how much he wants ...he will still be trapped inside a barrier and even while repelled,the Bijuu Bomb can explode at any moment and can Juubito can chose not to make it come into contact with Shinra tensei and land aside considering it busted Kumogakure ...It will leave Juubito to wonder if there is even a cell of Madara which can be found as remnants...on a side note PS' defence will be completely massacred while Juubito will still be in his Onmyoudon defence.
I think Obito was unable to use Kamui and possibly the rinnegan as TTJ. But regardless, it doesn't matter. He has TSB and can pretty much destroy Madara as an EDO if he gives him a good blow. Also, despite having Sage Mode, he doesn't have the fire power to take down Obito. Naruto had greater fire power and was unable to do so. He also won't be able to pull the Bijuu out of him on his own. He won't even be able to get him in that position, let alone extracting them. It took KSM Naruto, EMS Sasuke, KCM Minato, probably Bee and the rest of the alliance force to extract the bijuu. Madara has no chance.
Madara's PS + Sage Mode isn't as strong as KSM Naruto and EMS Sasuke with Jugo or Kurama Susanoo cloaked + Sage Mode from Naruto. Any wood release jutsu that Madara uses get countered by TSB. And there is also the sword of Nunoboko, which is debatable if it can get contered by a PS + SM sword slash.
Madara can definitely provide some good offensive if i think about it, but just because he won't be able to extract the bijuu, i give this fight to Obito.
In the story, he initially didn't have control over the ten-tails and yes, he almost got teared to pieces by it. But he ultimately managed to gain full control. He also had 2 different TTJ appearances. One when he didn't have full control and one when he did have full control, and obtained those tentacle like things.
