So since this is my first post in...it's been awhile.
Most likely you guys are talking about the North American versions of Dragonball Z and Naruto. In this case, they suck large hairy dragonballs. The American producers cut out alot of the blood and swearing in both shows. In Naruto's case, they have cut entire episodes out before.
The Japanese versions are extremely better. There's no cheesy dialog, the soundtrack is much better, and the blood and swearing is all there. There's seems to be much less babble about useless knowledge in the Japanese versions. Most items Naruto and DBZ talk about are of interest to the plot in some way.
