personally im rooting for mara but i would not discard talon easily bc out of "thousands" of sith, she was hand picked to be krayt's leading hand or only hand.
I'm not aware of her feats in the comics but in the novels like Allegiance she has no feats even remotely comparable to beating Luke

although i admit that I am not very knowledgeable about lumiya, but as far as i know the only reason she beat luke was bc he was unfamiliar with how to fight a lightwhip, along with everyone else. but again i am not 100% on this.

Here is a direct statement from Mara about when she fought Lumiya. Its pretty vague but her ya go.
That's where I was when a female cyborg found me. She wanted to bring me back to Isard. I didn't want to go. So I didn't. Cyborg got my lightsaber but not me. Better luck next time. - the essential guide to the Force
Lumiya stomped Nelani in the physical clash. Telekinesis is a different story - they were about equally matched, but Lumiya was constantly talking to Jacen rather than focusing on Nelani and ended up being disarmed as a result.
And Mara probably wins. Her blaster didn't do much in her confrontation against Lumiya and I doubt it would do anything against Talon.
Hardly a stomp, she tagged Nelani a few times for some minor damage but ultimately Nelani was stronger than her in the Force and beat her. I'm pretty sure Mara and Talon are stronger than Random Jedi 432.
The text makes it clear Nelani was outmatched physically.
Lumiya lost Force power as a result of her cybernetics, but her mastery was sufficient to know a myriad of techniques and her Concealment was enough to hide her alignment from Jacen as per his own admission. As I said, she doesn't hold up to these characters Force-wise (in a combative sense), but her lightwhip's unorthodoxy makes up for that in some ways.
