Asajj Ventress vs Darth Malgus

Both are at their peak.

Malgus lol.

Ventress, easily.

Ventress.

Make it Quinlan Vos and Malgus may win 1 out of 10

Ventress is a dark adept. Malgus is a most powerful sith of the Old Republic era. I think the conclusion is obvious.

Malgus stomps.

Ventress without much trouble.

Ventress lesser to mid difficulty

Malgus

Ventress could barely handle Savage who isn't much more than a brute with a saber. Malgus has a comparable amount of strength with more skill and mastery of both lightsaber and force abilities. It's a clear win for Malgus.
