The test of all fightan shounen is how long it takes them to get to a Super Sayian point. a point where a power-up finishes a fight.
Bleach took a couple eps to dscover the start of their 400 power-ups per person.
Naruto took two arc to release the nine tails chakra.
One of the reasons Dragonball is so great is because it never reaches that point and the same reason why the first part of DBZ is better then the latter parts.
One Piece took 280 or so eps and 300 or so chapters to reach the gears, that's damn good.
