Marr soundly defeated a powerful Sith Lord (Darth Lachris*) in a confrontation in which he tested her abilities. Details in the SWTOR article The Price of Power.
Speed:-
Marr is immensely fast. He can move so fast that another even a fully trained Sith Lord can find it virtually impossible to detect him in motion.
Marr approached her with slow, deliberate steps, hands resting on the small of his back. Her master never rushed, always maintained an appearance of control. "I sense a similar hunger for power in you. Do not bother denying it."
"I see no reason to."
In an instant, he was gone. Her nostrils flared slightly as she tried to sense his presence.
"You believe you have earned that power, but you are mistaken," his voice thundered behind her.
She did not flinch. Lachris had been Darth Marr's apprentice long enough to know when he was testing her. He pulled out his holocom to display the Nevoota system and zoomed in to focus on a single planet.

*About Darth Lachris:-
A powerful Sith Lord with a despotic temperament, Darth Lachris has never failed in war. Her successes in the Empire's battles have brought her to Balmorra, where she faces the challenge of putting down a resistance that has remained one step ahead of the military since the fight for the planet began.
Darth Lachris is sharp and wary, expecting a scheme behind every action her enemies take. Trained by Dark Council member Darth Marr, she is a warrior at heart with an embittered understanding of political necessity – and a lust for all the galaxy’s bloody pleasures.

Marr have endured severe wounds and decay with his power.
The Sith are notorious for wearing elaborate armored robes and intimidating masks to hide their true faces. These majestic guises are inspired by ancient Sith legends and mythology, projecting a terrifying image of dark omnipotence. The regal Darth Marr hides his face behind such as mask. Rumors surround Moff Xerxian's private audience with Marr, after the Moff failed to quell a violent uprising on Sullust. Supposedly Marr removed his mask and Moff Xerxian gazed upon the Dark Lord's ruined visage. Afterward, the Moff dictated a letter of resignation, and then shot himself.

But beneath Marr's armor lies a mind and body transformed by decades of immersion in the dark side.

The most impressive thing I find is being able to stop an assault better than a planetary shield. That's simply referring to his strategies yes?

These things and more."
