at the moment wher e I am at is episode 194 so i just finished the skypea arc i really liked the episodes about montblanc norland its actually a well thought out story with in the story. my least favourite part so far was the battle of alubarna it was unnaturally bleak to me
Arabasta was strung out quite a bit, but the story arc wasn't without it's merits. It almost seems like forever since that happened for me...
Most of the story arc's I have enjoyed. Skypiea is particularly good because the enemies are different to normal and Usopp gets a nice part with using "dials". Also, you find out a little more about Robin who only recently joined the crew at this point.
I particularly like what happens next after Skypiea
when they use the Octopus Luffy found to float back down and land in a huge Marine base G-8 (note: this only happens in the Anime, according to One Piece wikia). I thought it was cool

I should try and pick out episodes I like from each arc, because there are so many!
