It's interesting to think about how difficult it is to define "fair" with the current system. If a state's population is 60/40 and there are ten districts, do you want them each to be representative at 60/40, and thus 10-0? Or do you want six districts one way and four the other way? In other words, there's a real tension between "competitive districts" and "representative outcomes".
This is missing the forest for the trees. You'd want them represented accurately at a local level along reasonable district lines, rather than intentionally being misrepresented with district lines so tortured that the shapes they make are said to resemble a lizard. Maybe that's hard but I suspect it gets a lot easier once the bad-faith decision-makers are removed from their decision-making power. In the context you present, "competetive districts" means precisely the same thing as "representative outcomes".
