Finally getting around to watching DBZ, which fillers are worth watching?

Watching Z Kai because 300 episodes is a bit many for me, is there any good fillers to watch? (the rough kai episode equivalent would be nice if you can remember the rough time period) Planning to binge all of the Saiyan Saga in a sec since it's 5:30 in the afternoon and I have nothing better to do so fast response would be greatly appreciated! Already aware of most of the major plot points so don't worry about spoilers. (maybe do spoilertext them in case someone without knowledge of the story comes here for answers off of Google or something)
