Much as I love Sarah as a character, she never struck me as very interested in her writing career. Lois was always keen to hunt down a story. So Lois would get the scoop. I like Sarah better to hang out with though.
If the caped and scarfed one are elsewhere and have no involvment, then I’d say that Sarah-Jane saves the day AND beats Lois to the scoop. Lois just dies.
Just based on my own experiences watching/reading both “universes”, Sarah-Jane proved herself to be resourceful, capable, and self-reliant. She even came to the Doctor’s rescue more than a few times. Lois on the other hand always seemed like a simpering victim. She was always blundering into stupid situations where she had to be rescued. Without Superman on the scene, she’d be toast.
For cripes sake, Lois couldn’t even figure out that Superman and Clark were the same person!
THE SHOVELER: “Oh, not this again! Look, we’ve been over this. Lance wears glasses, and Captain Amazing doesn’t!”
MISTER FURIOUS: “Well, maybe he takes 'em off when he transforms.”
THE SHOVELER [exasperated]: “Then how could he see?!”
