Lol, I'm 22 years old, In other words I grew watching the Dragon Ball Saga and Saint Seiya... But the true is that DBZ is not good as Dragon ball. If the polls were about Naruto vs Dragon Ball, then I would go all the way with Dragon Ball. But is Naruto vs Dragon ball Z.
Dragon Ball Z for me it represents the downhill of the saga, Dragon ball had comedy, story and good fights. Dragon ball Z was all about of fights, that's all. The plot was borin, it wasn't interesting and basically destroyed many of my favorites characters, they became from secondary characters to useless characters (Krilin, Tenshi-han, Yamcha, Bulma), Basically the serie/manga ended being Saiyan-jin Z, the Dragon balls became from the goal of the story to just a third hand tool which were very easy to collect.
just my 2 cents.
