User blog comment:Undead RVD/Battle of the Telekinetic Killing Machines!: Jack (Subject Zero) vs Ermac/@comment-422690-20130326172014

I'm going with Ermac here. The reason why is rather simple: in a battle between two telekineticists, the slightest opening is a recipe for disaster. Since these two are both immensely skilled, Ermac can easily take advantage of any openings Jack's mental state presents. On top of all of this, Ermac's powers can be used to rip Jack to shreds - something she doesn't have a counter for. Jack can't take advfantage of anything "anti-magic", since it's just her, and Ermac has teleportation to counter all the movement-based powers and the area-based Warp power.

Note that I haven't played MK nor have I played ME, so if there are any flaws here, point them out and I will correct them.
