You can notice on other characters how their skills reflect how they went on to pick different tools to achieve their goals as ninja. Kakashi's is all about cornering an enemy to finish it with a Raikiri, Naruto's is all about ME GRUG HAB MANY GRUG ME SMASH because he never bothered to learn a single nature transformation before getting into important fights, Tsunade/Sakura's focuses on survivability so they can stay in the battlefield to keep healing their allies, Gaara's restrains and crushes his opponents, and so on.
