That's how I feel. DBZ is the best anime there will ever be in my opinion while as an anime DBGT is pretty good. At first I loved GT, then for a while I hated it, & now I'm starting to rekindle my love for it. I recently bought some GT DVD's from both the Bebi & Super 17 saga. As for DB, I like it but I don't really care for it because the fights aren't as interesting as in DBZ except for maybe the 17 year old Goku vs Piccolo fight.
Cell was the literal definition of badass. No one is on par with him (except for Broly, THE KING OF KINGS).
I'm watching GT right now (the last 4 episodes) & man, this series was great. I think all of the sagas were great. However, Super 17's saga was a bit too short, especially since he was a great villain. In any case, I may be the only one but I want more DBZ movies to be made so that we can have more villains. More villains equals more playable characters for DBZ video games.
