The Don Krieg arc was average IMO. Also, the execution of the Skypiea arc being great was mostly thanks to Enel. Without him, it would have been average as well (I mean seriously, it was nothing amazing story-wise). Also, the CP9 arc was like the Arlong arc x1000000000. The Alabasta arc was alright in the beginning (since all they were during was walking to that city) but the second half was epic. The arc ranking goes like this for me
1.) CP9 arc (BY FAR)
2.) Sabaody Archipelago (The ending of that arc is what did it for me)
3.) Alabasta arc (EPIC)
4.) Arlong arc (Luffy FTW)
5.) Skypiea arc (Great arc because of Enel)
6.) Impel Down arc (The second half was awesome but the first half was SO BORING)
7.) Don Krieg arc (Average arc other then the Zoro vs. Mihawk fight)
8.) Thriller Bark (BY FAR the worst arc in One Piece, it only got good in the end of it)
I won't rank the Marines vs. Pirates arc until its done. But so far, it would rank above the Impel down arc but below the Skypiea arc for me.
