I'm going with a 7.0
I tried to watch the show but I never found something to really hook me. Most anime that I watch have either a concept or a character that really keeps me watching and wanting to know what happens next.
Bleach had Kenpachi and DBZ had Gohan(during the Cell saga and beyond). Kenpachi is just badass, fun, and intelligent enough that for me he never felt forced into a a specific stereotype. You knew that when he got there he was just going to kick some ass with no super long flashback or having to reveal a huge secret.
Gohan was someone we watched grow up on-screen much like the Harry Potter actors. He first was a baby with large potential, then a young kid with the ability to go toe-to-toe with the mooks, then a few years later he has the same personality but has matured, becomes the cold blooded SS2, becomes a teenager with a funnier but matured personality as we see him get Videl and unlock his real potential, finally we have him as a suit wearing dad who when the time comes will kick ass just like he used to.
