I'm going with Water 7/Enies Lobby I have to put them both together.

Water 7 had the best exposition in the Manga, by far. In the introduction to Admiral Aokiji, how he put fear into Robin's character, and the fight with Luffy and the crew. Also I loved how how great the fight between Usopp and Robin was. Enies Lobby expanded the story even more when it came to Robin's flashback, and the Luffy v Rob Lucci is the best fight in the entire series for me.
