I watched dbz and didn't get to dragon ball until long after it went off the air, so I like dbz better because it was apart of my childhood. But the show did have several flaws, like I found it annoying how dbz made humans useless and just punching bags for the villains. Even Piccolo was eventually down played by the show, basically if you weren't a Saiyan then you always get your butt kicked and then would have to be rescued by the Saiyans.
