What's the difference between Haineko and Senbonzakura?


What's the difference between these two _shikai_ ; Rangiku's **Haineko** and
Byakuya's **Senbonzakura**? They both seem to have the same abilities.




For Matsumoto Rangiku's shikai:

> When released with the command "growl" (唸れ unare?), the blade dissolves into
> ash. In combat, Matsumoto can control the movement of the ash, and cut
> anything it lands on by moving the hilt. The ash is also solid enough to be
> used as a shield to block enemy attacks

For Kuchiki Byakuya's shikai:

> ...Senbonzakura's blade separates into thousands of slender, petal-like
> blades.... While the blades are too small to be seen by the naked eye, they
> reflect light in such a way as to appear as cherry blossom petals. Byakuya
> can control the blades at will thereby allowing him to shred opponents at a
> distance and break through almost any defense. While Byakuya can control the
> blades with his mind alone, using his hands allows him to do so more
> effectively, making the blades move twice as fast.

There seem to be a few main differences, though they are very similar.

  * Byakuya can control the blades of his with his mind, while Matsumoto needs to move the hilt.
  * The ash can be used as a shield while Senbonzakura cannot.
