The more I think on it...Nakama shouldn't even be a category.
The Konoha 11 aren't really officially a group, it's just something the fans made up that took a role in anime filler. The appearance of the group in the manga was just them deciding that they were going to kill Sasuke and then live it to Naruto later on. That's all the group ever did as a group. I can't even justly call that a Nakama. Team 7 is closer but even then that's a broken Nakama that's trying to put itself together. Really, the closest thing Naruto ever had to a Nakama was the Sasuke Retrieval Squad. They had a set goal, were friends, and were willing to go the distance for one another. The only reason this isn't one is because the group doesn't officially exist after the arc. Naruto has no set Nakama so there is no way for it to compete.
Bleach on the other hand has one. It's just woefully irrelevant. I disagree with him about Ichigo not really having a reason to be friends with them. He does, with all of them. The problem with this group is very noticeable: When the Shinigami, like Hitsugaya, get more attention than the Nakama, they may as well not even be there. They aren't important in the grand scheme of things. The only thing the Nakama does is exist so Ichigo has a reason to fight the bad guy. The Nakama are so out of focus that it's painful and makes me miss the good old days of the Soul Society arc.
How can one actually put these two up against One Piece in this category? It is completely one sided. Each member of the group got a small arc dedicated to them. They have a conflict, Luffy shows up and kicks that conflict straight in the ass, and they become his Nakama. The purpose of the story, at least the very early parts, was the Nakama. In Naruto, no Nakama exists. In Bleach, it's so out of focus that it is irrelevant. In One Piece, it's the driving force for a lot of the plot. No shit One Piece would win that. If the category had been supporting cast or something, the others might have had a chance at the very least. I don't have a problem with One Piece being seen as better than the others(In many ways, it very well is) but don't insult the reader by making a category where the competitors are that unbalanced. It's not fair.
