Besides looking cool, you will deal more damage when Tidus have more HP. But subsequently you will deal less damage when Tidus' HP is low.

It all depends on one choice whether to have a full collection of the Celestial Weapon, also a point to take note of is a customized weapon deal constant damage in regardless of HP. (of course Defense or other stuff is taken into consideration....)
