Quite true. To me, there's a distinct difference between the GT and Super timelines at this point. I kinda view it like this.
GT: Bardock, Father of Goku > Dragon Ball > Dragon Ball Z > Dragon Ball GT
Super: Dragon Ball Minus > Dragon Ball > Dragon Ball Z Kai > Dragon Ball Super Broly
There's more stuff that goes into the GT timeline, but it isn't relevant to the topic at hand.
