What anime should I watch?

I've got a stack of anime that I could watch but I can't decide which one. I thought I might get you guys to choose. >:3
I would add Queen's Blade on but unfortunately all of my files for it got corrupted for some reason. :/8D:
Here is the list of anime I have:

Kurokami: episodes 1 to 12
Shikabane Hime Aka: episodes 1 to 9
Kanokon: 1-12
K-ON: 1-13
Code Geass R1: 1-21
Kekkaishi: 1-52
Rosario+Vampire: 1-13
The Third - Aoi Hitomi no Shōjo: 1- 24
Vampire Knight: 1-13
Zero no Tsukaima: 1-13
Naruto Shippuuden: 1-88

That is all the anime I have at the moment, ****** internet prevents me from downloading it.

 

I'm going to suggest Code Geass, simply because the only others I've heard of are Naruto and Vampire Knight. Naruto is fillerful and too long. Vampire Knight abuses anime-emotiocons.

 

Well I don't watch anime, but I've heard of Code Geass, so it must be popular.

 

It is.

Mind control+giant robots+politics+Large Ham Lelouch makes it a success.

 

Pretty much any of it except Narushit.

 

*shrugs* Death Note, anyone? <--- only one I know :sideways:

 

K-On, Rosario Vampire, Code Geass and Kanokon. In that order.

 

Code Geass. It's an amazing anime, I'm on R2, and I loved the first season. Plus the first theme song is nifty :3.
