I respectfully disagree.

Lord Scourge is a rip-off of Darth Bane and Raskta Lsu in martial aspects and Meetra Surik in the Force:1. During his time at the Academy, Scourge had discovered that there were many ways to draw upon the power of the Force. His natural talents had led him down the path of the warrior: learning to channel his emotions into strength and raw outbursts of lethal energy. (SWTOR: Revan)
2. "I have studied your records from the Academy and observed your battle with the mercenaries in my courtyard," she said at last. "You have a special gift. You do not just feed on the raw emotions of your foe; you gorge yourself on them. You feast on their primal fear. It amplifies your hate and anger. It fuels the power of the Force. It transforms you into an instrument of death and destruction." (Darth Nyriss to Lord Scourge)
3. SCOURGE WAS AN EXPERT SWORDSMAN; at the Academy even the instructors had been reluctant to face him in the training ring. When the dark side flowed through him, his blade was more than a weapon. It became an extension of his will. (SWTOR: Revan)
4. As the Sith Emperor's personal executioner, the grimly fatalistic Lord Scourge has personally killed more than a hundred Jedi–and ten times as many Sith. (SWTOR: Codex Entry)

Meetra Surik needs no introduction IMO. She is also powerful and battle-hardened. She participated in the Mandalorian Wars and proved to be instrumental in the downfall of the dangerous Sith Triumvirate. Martial skills wise, she matches Lord Scourge.

Regardless of the talents of Lord Scourge and Meetra Surik, this is how the battle unfolded between them and Darth Nyriss:
"Someone's coming!" Meetra said.
Scourge turned to the guards still sitting on the floor.
"Ready your blasters, you fools!" he shouted.
As they scrambled to their feet, T3 let out what could only be described as a shriek of terror. An instant later, the little astromech came tumbling down the stairs and bounced across the floor as if he'd been shot from a cannon. He landed in the corner on his back, his wheels still spinning.
"Get Revan out of the way," Scourge said to Meetra.
As she dragged the Jedi's unconscious body into the nearby cell, one of the guards drew his weapon, while the other rushed over and picked his discarded blaster up from where Revan had kicked it aside.
Scourge nodded at the guards. In response to his silent command they crept to the foot of the stairs and peered up toward the door above.
A burst of purple lightning arced down the steps, catching both men in the chest. They barely had time to scream before they were turned into charred and smoking husks.
Scourge took a step back, knowing exactly who had been responsible for unleashing the fury of the dark side against the hapless guards.
Nyriss made her way slowly down the stairs, the outspread fingers of her left hand still crackling with electricity. In her right hand she held her lightsaber, the blade humming softly. By the time she reached the bottom, Meetra had emerged from the nearby cell.
She ignited her lightsaber and came to stand beside Scourge.
"What's this?" Nyriss asked, her voice mocking. "Another Jedi?"
When neither of them answered, she turned her head to the side and laughed bitterly. "The Imperial Guard will make sure I never leave my stronghold alive," she told them. "But neither will any of you."
She raised her free hand above her head and fired off another burst of lightning. Both Scourge and Meetra threw themselves clear of the deadly electrical bolt, but in doing so they gave Nyriss the early advantage.
Before they could recover, she leapt at them. Despite her withered appearance, she moved with the all the speed and ferocity of a dark side warrior in her prime. She landed right between her two adversaries, her blade flashing back and forth in a series of slashes and cuts that immediately threw her two opponents on the defensive.
Scourge barely managed to parry the first wave of her assault, unable to even think about countering with an attack of his own. Another quick thrust forced him off balance and he staggered backward.
Nyriss seized on the opportunity to focus all her efforts on breaking through Meetra's defenses. The Jedi was clearly overmatched; though she managed to hold her ground, she was forced down to one knee.
In the awkward position her right flank was exposed and Nyriss brought her blade in to deliver a crippling cut. At the same time, Scourge lashed out with the Force, catching Nyriss flush in the center of her chest.
An ordinary foe would have been thrown clear across the room, but Nyriss instinctively threw up a Force barrier to protect herself, absorbing and redirecting the brunt of the impact. Even so, Scourge's attack knocked her off balance just enough to send her lightsaber wide of the mark, giving Meetra the opportunity she needed to scramble away to safety.
Scourge rushed forward, hoping to drive Nyriss back into a corner, but she met his charge with an invisible wave of rippling energy. It picked Scourge up and tossed him head-over-heels, sending him crashing to the wall.
Dazed, he looked up just in time to see another bolt of violet lightning catch Meetra in the chest. Like Nyriss, she threw up a barrier to save herself from the worst of it, but she was still knocked from her feet.
"Did you think I would be as easy to defeat as Xedrix?" Nyriss shouted, raising her lightsaber triumphantly above her head.
The air around her began to crackle and grow hot as she gathered herself for the killing blow. Scourge felt the energy building inside her, and he knew he would be powerless to stop it. Nyriss was too powerful; her command of the dark side was too strong.
"Gaze upon me and see your doom!" she declared. "I am Darth Nyriss, Lord of the Sith. I am the conqueror of Drezzi, the destroyer of Melldia, and a member of the Dark Council!"
Scourge braced himself for the end.
Her performance is arguably even more impressive then that of Darth Sidious against the brothers; it can be safely argued that Lord Scourge and Meetra Surik are more skilled and accomplished warriors then the brothers. And yet this duo of powerful and accomplished warriors terribly failed against Darth Nyriss.
