Scourge has killed over a thousand Sith Lords and 100 extremely powerful Jedi in battle, he has 300 years of battle experience and training under his belt (which is likely immense given that in a mere 30 he was a master of at least 3 lightsaber forms), for 300 years he's been above the Dark Council and has kept them in line, he's amped by Vitiates power and he has extremely good, lightsaber resistant heavy armor.
His life being artificially prolonged by a combination of invasive and perverse technology and powerful dark side forces, Scourge has dutifully served the Empire for over three centuries. In his service, Scourge has struck down dozens of Jedi while climbing over the bodies of numerous Sith who dared to stand against him."

“Entire generations of the Sith Dark Council have passed under the watchful eys of the Emperor's personal executioner, the grim Lord Scourge. As the feared “Emperor's Wrath”, Scourge enforced his Master's will for more than three centuries. When a Jedi grew too powerful, or a Sith too ambitious, Scourge eliminated the threat.”

"He's sending his personal executioner for me. His wrath incarnate. I'll be punished for my crimes."
"Who is the Emperor's Wrath? A Sith Lord?"
"A ghost. Older than anyone except the Emperor himself. Even the Dark Council fears him."
-SWTOR (Sajar and the Hero of Tython)
"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."
-SWTOR: Revan (Darth Nyriss to Scourge)
''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
"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. Even the most powerful members of the Dark Council avoid offending the man bearing the title “the Emperor’s Wrath.” Lord Scourge has dutifully served the Empire for over three hundred years, his life unnaturally prolonged by perverse technology and his master’s dark side powers. Centuries spent watching his fellow Sith Lords rise and fall has given Lord Scourge a unique perspective on people. He can analyze someone’s flaws after only brief observation, and freely shares his perceptions (whether they’re wanted or not)."

If Scourge has a way of keeping Sion down, he's got this.

Considering Scourge's ample superiority as a duelist, and Sion's lack of offensive force application, i'd like to think Scourge takes a solid majority.
