It's funny....the episodes that most people mentioned already and are probably going to mention are not the ones I found myself revisiting. Not because they're not great in fact Twilight of The Apprentice is one of the best pieces of Star Wars content ever produced.
It's just something about the consequences of each of those episodes. I personally like the random one offs like through Imperial eyes or The Honorable Ones.
Again this is just about revisiting so for me it's got to be an episode that doesnt have massive consequences and I can passively watch. Because of that I find myself loving solid one off episodes.
