I'll give my opinion, only counting finished series, so:

1. OOO
2. Double
3. Blade
4. Ryuki
5. Den-O
6. Fouze
7. Kabuto
8. Kiva
9. Wizard
10. ZO

From what I've seen, I'd probably rank Amazon around the 6th, Agito around 7th, and Faiz around 10th, but I haven't finished those 3 series, so I can't give a proper ranking.
I know Wizard isn't over, but unless these last 10 episodes are jaw dropping levels of amazing, I'm pretty confident at that ranking.
Just because the likes of Wizard and ZO are at the bottom doesn't mean I consider them to be bad. They're just not as good as the others, is all.

Putting Decade on the list would be an insult to everything else on the list. So to not go on some spiel about it, let's just say "I consider it to be the worst show" and end it at that.
