Madara, he can use paths power, susanoo,meteors and wood release plus even the nine tails is afraid of him.
Tobi is seriously overrated, he's nothing more than a ST ninjusu spammer who steals powers from others and claims it as his own. He stole the Rinnegan, plus his jinchuuriki paths were provided to him by Kabuto as a gift of hospitality and alliance, other than that Madara would beat him. Madara has EMS, the Rinnegan, Mokuton, Immense shinobi skill and prowess. Tobi has the basic sharingan, one rinnegan, 6 jinchuurikis, ST ninjutsu and average fighting skill. Madara>TobiTOBI would own Madara at the current level.
He doesn't have to hit him in the way that Minato, Torune, or Fu tried to, check out Chapter 510, page 3; Tobi can only remain intangible for around five minutes.i think tobi, nobody has proven fast enough to hit him since Minato so I don't see him being able to either.
You don't have to be super fast like Minato to beat Tobi, check out chapter 510, page 3. Tobi can't stay intangible forever; Madara would just need to do something similar to what Konan did, but twice because of Izanagi.We still haven't seen what the new "tobi" is fully capable of... it's hard to say because of that.... but I will got with "tobi" even though madara's susanoo is freaking amazing!! I don't know if tobi has susanoo though.... but "Tobi" is impossible to kill without being super fast like minato and I am pretty sure that madara doesn't know Flying Thunder God Technique. If "tobi" has all of the powers of nagato then definitely him!!!
sorry forgot to mention that , edo madara , and dont jump to conclusions we havent seen what tobi can do other than transport himself or other ppl , control 6 paths and become intangable , we havent seen his MS techniques or which rinnegan techniques he can use , for example , shinra tensei , which madara as far as we know cannot use , thats why i thought of this threadedo madara or madara??
madara would lose but edo madara and tobi will make a close one..
i personally think tobi would win but it can go on either side
