I wish i could get you the sub. It's not even worth putting the cartoon network dub on here because it's a disgrace to the most memorable death scene in naruto if not all of anime. To see it, watch the unedited ep 19 sub. "zabuza disperses into the snow."
Almost everything in the Forest of Death Exam is good stuff
This fight, Orochimaru vs Kyuubi, the last two episodes of Sasuke vs Itachi, and Kyuubi vs Pain are stand out for me.
I think the story of Naruto is straight but imo it's only straight enough to sustain me between the great fights. My favorite episodes are all the ones with well animated fighting in them. I can't think of any 100% drama or comedy episode that stands out in my mind. The closest I can think of Asuma vs Hidan where it was a fight, but it was mostly just talking for two episodes.
