Half Blood Prince really the best book?

Majority of people I know who love the series (not many I may add.. many of friends are like allergic to reading) they all say Half Blood Prince is the best? I'm still pretty undecided about which one is the best? I personally think either Deathly Hollows or Order of Phoenix were the best but I'm re-reading the series and I'll see if I get my mind made up.

haha Navi, even i thought the HBP was the best.

I don't agree that Half Blood Prince is the best book. Yes alot happened in the book, however, personally, it didn't resonate as much as DH, OOTP and even POA.(which is my personal favourite) 

i personally liked da deathly hallowd da best....n found ootp boring...just like da muvi.....dunno y.....but i like COS too.....

so i guess for me its a tie between COS & DH

the half blood prince is really a good book you should read it

for me my Most fave HP books are HBP and DH...but comparing both of them I definately love Deathly Hallows.

I love Deathly Hallows the most. HBP was really good, but DH was the best because it tied everything up and the Battle at Hogwarts was aMAzing! Honestly, I have no words to describe it, and I really enjoyed the whole story with the Deathly Hallows.

I like Goblet of Fire the best!

I liked Deathly Hallows the best:)

I like Goblet of Fire the most coz it was mind blowing...!
