I agree. Although I do believe Haku had much more potential then Zabuza because of his blood line and the fact that he sorta directed Zabuza to victory in his battles I think Zabuza is more skilled in ninjutsu. Infact I think many jounin and genin are taken forgranted because of the few who have certain outbursts. In other words even though Naruto has the kyuubi I still think Itachi or Orochimaru could take him out, possibly even Kakashi. Although the few have great power they tend not to use it in combonation with ninjutsu often.
