User blog:AdmiralK/OP greatest arc/story

What OP arc/saga is the best?

for me it has to be sabaody archipelago the ending is just legendary i love it. it was also very sad i really felt for luffy:(

but the one story that i really disliked was the sky island to me it was really lame (sori to every one who like it) so i just wanna know what you guys think is the top part?
