[Guyver Spawn]

Kai is better than DBZ in my opinion due to better placing seeing there is not much filler. Most of the filler in DBZ didn't add much to the plot in my opinion. Not to mention the English dub for Kai is the best English dub for DBZ in my opinion. You can watch it Uncut on DVD, Blu-Ray and Toonami.

I find the old dubs from Funimation for DBZ to be pretty terrible in my opinion. They have bad voice acting, corny dialogue and bad dub errors in my opinion.
