Hibiki was my favorite as well. Paradise Lost is really good for its action and parallel universe story. Blade was okay. I kinda liked the obvious plot twist.

As far as the main riders list:

Agito-Shouichi/Agito Burning Form
Ryuki-Shinji/Ryuki
Faiz-Takumi/Faiz
Blade-Kenzaki/Blade
Hibiki-Hibiki/Hibiki
Kabuto-Tendou/Kabuto or Kagami/Gattack (cant make myself choose)
Den-o-Momo/Ryoutarou/Sword Form

Basically the same as Kev but with a bit of a twist in there somewhere.

I guess with Agito, I just didnt like the idea of that dude being basically god and calling all humans his children. I know its just a story and pretty picky of me. But I tend to not like stories that go in that direction. If the story went a bit of a different way but keeping the same logic, I would have enjoyed it a lot more. IDK.
