Sakura, in my opinion Tenten didn't improve or change that much from Naruto to Naruto Shippuuden, whereas Sakura did a lot. Although I gotta admit that I don't really like either of them fighting.
I only have seen the anime and didn't read the manga, but I would definitely go with Sasuke. Although I like Naruto a lot more, Sasuke just needs to use his Amaterasu and there's nothing Naruto can do.
His Bankai would be bad-ass for sure, but atm I see him as a captain that's able to fight for not more than 5 minutes until he caughs up blood and becomes useless..
Orihime, no doubt. She's whining all the time, and compared to the others her abilities didn't really improve.. ---------- Post added at 07:02 AM ---------- Previous post was at 07:00 AM ----------
I really like the beginning of the fight btw Ichigo and Byakuya, when he blocks that Phoenix-thingy, saves Rukia and the fight begins. But there are so many great moments
Vizord, definitely. I always try to get stronger in RL too, therefore if I 'started' as a Soul Reaper I eventually would have broken the barrier btw Shinigami and Hollow to become a vizord.
During my childhood I was a huge fan of DBZ, but nowadays I would say Naruto is a lot better. It really has a plot, the characters aren't as superficial as in DBZ, and Naruto can also make you cry, which I don't remember DBZ every made me. Definitely Naruto! :-)
Naruto vs. Pain was really good, but I think the best one was Kakashi and Naruto (and Shikamaru, Ino..) and the two "undead/immortal" guys from the Akatsuki! (unfortunately don't remember the names!)
