Gaim's definitely in my top 10. I'd probably place it around the five, six, or seventh spot.

1. Gaim

6. Kabuto

5. Fourze
6. Faiz
7. Blade

I only have a top 7 for now. I haven't watched Kuuga and Black, haven't finished Den-O, don't like what they did to Hibiki halfway through the series, and I don't like Kabuto or Kiva enough to put them on the list. Blade only barely made it onto the top 7. Faiz is there mostly for the fond memories I had watching it in my youth

Gaim actually managed to push Ryuki out of my top spot. It was that refreshing. Pun intended.

I think for me my rankings would be (now granted I only had watched a handful of KRs and still hadn't finished a couple of series but...here it goes):

1. W
2. Fourze
3. OOO
4. Ryuki
5. Kabuto
6. Agito
7. Gaim
