Legend of Korra because:
-darker subjects (yessss!! There should be a PG-13 version!! That would make me a happy girl!!)
-romance (Shipping Wars part- Makorra absolutely KILLED me)
-YEAR LONG WAITS in-between Books
Those are my reasons why I love and hate LOK.
-funny jokes (I've used some of Sokka's lines on my teacher XD)
-shorter waits for Books
-geared toward younger kids (UGH!!! I'm almost 13, for crying out loud!!)
- little to no romance (how can you write good FanFics?!)
So yeah. Legend of Korra is better. Don't hate me.
