Best One Piece arc so far?

What do you think is the best One Piece arc so far?

For me, it's Alabasta - it had a very complicated plot which was executed really well in the end, along with a great Luffy vs Crocodile fight. After that, it's Water 7, which revealed some people's backstories and gave Luffy a revelation at the end of Enies Lobby. I haven't enjoyed Thriller Bark so much, and East Blue was a bit haphazard.

I'm entering the Summit War (Whitebeard War) arc which lots of people apparently enjoyed though, so we'll see what happens!



Edit: I haven't finished the Whitebeard War arc, but I'm changing my vote to it - all the islands involved in this arc, and the story itself, has/ve been fantastic!
