One Piece > Bleach >> Naruto
What made Marineford so good was the fact they were there to save Ace. All their efforts were put into that single point. Not to mention we saw the biggest badass of the series wreck havoc and destroy Marineford.
Bleach is good because of the fight scenes. The motivation isn't a big factor because it is just about kicking the other teams ass because of a 1000 year grudge. Bleach may become better, but its difficult to compare when the war is just beginning.
Naruto well..... it was hyped to be really good, but then so many people got trolled by how they were beaten and it became blah. The sense of danger left. Then Madara showed up and it was holy shit, hes going to kick a few asses. Then the whole Tobi thing happened and then it went to shit. After this last chapter though, it may have a really good ending to redeem itself.
