Guy after fighting Madara. Keep in mind that Gyuuki is also in pain.

Hachibi restrained.
Guy needed to use his strongest known attack just to get a hit in on Madara while it is very obvious that Madara is having fun.
Oh and before you whine about how you weren't talking about how bad Bee and Guy are getting beat, consider that if they weren't there at all then Madara would be wrecking Naruto. As it stands he has taken some of Naruto's chakra while Naruto has done nothing to Madara. This means, in layman terms, that Madara is winning.
And no, he explicitly fought the battle for the Senju cells.

That is a canon fact from Tobi, who knows everything about Madara. Oh and got his ass whooped?

Hashirama looks pretty hurt if you ask me.
And it's cute how you try and use the bias excuse on me as if I come in here to express my butthurt over Naruto's successes(which you do with Madara I might add). I could easily make the argument that he was given shit but I don't because while he was given some things he had to work for others. The same is true for Madara. They're here now because of his foresight, planning, and ability to adapt to the unexpected. Get over yourself. I'm not saying I like or prefer Madara over Naruto, I'm saying that regardless of bias, Madara is winning the fight between the two because the only person to land a hit on him so far has been Guy. This isn't an opinion, it's a fact.
