The Xcution arc kind of fell into being a standard training arc within the past few episodes, I'm hoping it can pull itself out of that. Considering that Bleach has always been predictably training arc -> rescue arc -> training arc -> rescue arc -> ad infinitum, I wouldn't hold out much hope for the next arc.
I know you praised One Piece in your spoiler, but even it's in a rut. The Fishman Island arc has been the worst major arc in One Piece since Skypiea, though the past three or four chapters introduced some plot elements that felt like classic One Piece and it might get back on track soon. SJ is still very ripe for a newcomer with good ideas to come along and claim a spot amongst the big three.
