The Cell Saga is arguably the greatest arc in Dragon Ball Z. It features some of the series' best fights, most emotional story beats, and fan-favorite new characters like Trunks, the Androids, and Hercule. Even for fans who don't agree that it's the best arc in the series, it's hard to argue against it being a comparatively better ending for the series than the Buu Saga was.
