I need some opinions on these animes, please! :3

Okay, I need a new anime to watch on Netflix, and I was considering one of these four...
• Canaan 
• Dance in the Vampire Bund
• High School of the Dead
• Sekirei
If you've seen any of these, could you maybe tell me what you thought of them? And if you've seen more than one of them, could you also possibly say which of the ones you've seen you prefer and why? I appreciate your help. :3
