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 anda maybe tell me what anda thought of them? And if you've seen lebih than one of them, could anda also possibly say which of the ones you've seen anda prefer and why? I appreciate your help. :3
