It’s tough to decide.

Empire has double meaning as if you’re watching in release order you assume that Darth Vader is the man who who killed Luke’s father, only for it to be reversed on its head. Both literally and figuratively. It also has a truly unique setting of rings within rings. Different dimensions if you will.

Jedi has the more immediate and emotional context. It’s interesting having the contrasting force of Palpatine in there to plant dark deeds he’s been planning since The Phantom Menace if you’re watching in chronological order. It’s concluded with redemption and the end of the Palpatine’s reign.

So? My conclusion is I’d lean Jedi because it has the greater sense of formality as it truly interweaves both Anakin and Luke’s story to bring them both full circle to conclude the six part story.

I do think Empire has the better setting though.
