So, my little cousins are into this as well as my little brother. I don't mean into it like, "Oh man, that's so cool!". I'm saying they actually take lessons. My little cousin is already a green belt, and he's quite the little karateman

I've always been into karate (martial arts, whichever you prefer), and hope my mother puts me in sometime soon. Anyway, the thread.
I know that there are different types of Karate (or martial arts?).
-Tae Kwon Do
-Shorei-Ryu Karate
-Jiu-Jitsu..
And I know there's a whole lot more. But would any of you know the differences in style between them? Which is the most advanced type of Karate? I've heard it mentioned before, but I can't get my tongue on it now.
Thanks!
