Hard to decide.
Bleach is last, what with not a lot happening and Sasikibe being alive *sigh*. Though I suppose there is some decent build up.
Naruto is vying for first, what with the continuation of the Madara fight and Madara being awesome. Tsunade was cool too. Bogged down by the the switches to Dan's perspective and an ending that's a tad rushed.
One Piece was bogged down in the beginning because these G5 guys are just boring. However, the humor was much better, particularly Robin's imagination and the reveal of who was behind it was good...
Lets go with....
1. One Piece
2. Naruto
3. Bleach
One Piece wins for me!
Hm, I kinda like Bleach this time. The reveal at the end of OP helped too.
This is a *very* close one, all three were strong.
Maybe Bleach 1st, OP and Naruto tied...? Or Bleach and Naruto tied followed by OP... yea, I think that one.
And I'll include the latest Fairy Tail and Claymore chapters in my list at 4th and 5th. But even FT was pretty good, those two were just more setup than the other three.
