I probably like drama the most. Even when it comes to action, it's primarily the drama of the battles that keeps me hooked. Kenshin, Soul Eater, and to a lesser extent, Yu Yu struck a great balance between action, drama, and comedy. Of course they have different types of humor too.

For that matter I actually read a little bit of Fruits Basket for the humor, but it was ultimately too girly for me and I had to put it down. xD
