Holy crap, I never finished talking about Yu Yu Hakusho. I finished it a week ago.
The Chapter Black arc (or whatever the hell it's called) was okay. I honestly don't remember much about it. Except the ending, and Kuwabara doing almost nothing really. They said he was important to the plot, but he did almost nothing of consequence the whole arc. And he wasn't even present for the final one.
Anyway, the big showdown with Sensui was pretty awesome at first...
Eh, it was okay. I feel the same way about the final arc. It had a very interesting back story though. I kind of wish it didn't just end in a tournament though. Overall, I say Dark Tournament was the best, but the later two arcs are close. Yu Yu Hakusho at large is pretty good, but definitely not the greatest.
