Yeah, it's the same animation style they used during Sasuke vs. Orochimaru(Chuunin exam), Oro vs. the 3rd, and Naruto vs. Sasuke 2, two of those you listed as your favorites.

That's basically their "go to" animator for their most badass fights. The thing is, they rarely use him for entire fights. He usually just does one entire episode, and since fights like that are rarely ever one episode long, he usually just does the most action intensive episode of the fight.

For the record, I'd say my favorite fights are:

5. Sakura & Chiyo vs. Sasori
4. Lee vs. Kimimaru
3. Team Shikamaru vs. Hidan & Kakuzu
2. Naruto vs. Sasuke 2
1. Lee vs. Gaara
