Malgus vs. Wyyrlok
Marr vs. Talon and Nihl
Satele vs Stryfe
I feel like Satele would body Stryfe before either of the other two sets of battles conclude, thus giving team TOR the advantage. Maybe Wyyrlok finishes Malgus first, but I doubt it given his insane power in his own right and nigh-unprecedented durability to boot.
If Satele is using BM, thus “greatly increasing” the capabilities of Malgus and Marr and weakening the Legacy Team, I could see:
Malgus vs. Wyyrlok and Nihl
Marr vs. Talon and Stryfe
Where Marr puts down Talon and Stryfe before Wyyrlok and Nihl are ever able to put down Malgus, and I think BM amped Marr + Malgus would definitely take Wyyrlok.
I”ll go with Team 1.

Darth Marr's extraordinary speed is a factor, and he have humbled entire armies during the course of the Great Galactic War much like Darth Malgus. His dueling skills are stated to be second to none, and he was strong enough to hold onto his seat in the Dark Council for decades. He met his match in (enraged) virtually immortal Dark Revan but so would 99% of the Force-users.
He's potentially stronger than The Wrath and Darth Nox via the quote which says his abilities are second to none post Act 3 which would logically include The Warth and Darth Nox.
