One Piece, Radiant Recommendations
Both have great world building and a large caste of characters. Both have two main factions that have conflicted members that you can root for.

They share a charming sense of adventure and mystery that keeps you wondering what the next step in the journey is and who the new interesting characters you'll meet along the way.
