i prefer "Ninjutsu", "Taijutsu", and "Genjutsu", because the similiar naming helps to emphasize that they are linked together.

What bothers me the most though is when they call Taijutsu "Hand to hand combat".......especailly when the character in the show references it alot...because then the sentence gets all long-winded, and it doesnt sound like he's actually talking about a technique, but rather just random punching.
