Obviously, I disagree with a number of your premises. In order:
(1) Kreia sat down for several minutes prior to using the attack on the Jedi masters; it is not unusual for powerful techniques like this to require some sort of charge time. Look at Dooku, whose assault on Yoda is temporarily stopped while he initiates various TK attacks.
Already refuted by Neph. The point is, assuming a prep time when there is no such evidence is silly. You could suddenly assume prep time for a defense, prep time for TK, prep time for precog, etc. It opens up into endless and ultimately fruitless discussion and debate without factual evidence or even basic common sense backing it up.
(3) Vader has experience resisting attacks on his command of the Force. The Dark Reaper uses just that kind of assault. Through Luke's account of learning the weather control technique in one of the more recent books, there is an instinctive method of learning new techniques similar to those already mastered. In that book, Luke just cycles through different mindsets until he discovers a new way to levitate an orb using electric charge. Vader, equipped with much the same connection to the Force, already has a technique known to defend his Force presence. It is a simple and instinctive matter, then, for him to resist the drain for some amount of time.
This is a huge conditional:
If Vader's ability as taught to him by Ulic is sufficient enough to withstand Kreia's ability, and if he can enact it in time to avoid being drained (which assumes heavily that he is familiar with his opponent's use of the technique and that he recalls an ability he hasn't used but once in twenty some years), then it stands to reason he has a chance against her.
You can bawl all over about his historic connection to the Force all you want; Vader's potential is not realized, and his actual showings - while impressive - lack the finese and esoteric knowledge of older, established Sith such as Kreia, who had a world's worth of Ancient Sith artifacts, archives and energy at her feet.
It is ludicrous to suggest that Vader's Force defense (which is largely an instinctive measure, according to many sources [See Zannah's first appearance, Mace in Shatterpoint, and even Maul against the Nightsister]) would be at the same level as the Jedi Council of KotOR II. Vader is equipped with a historically unique connection to the Force and the knowledge of how to defend against similar attacks. Kreia's other victims have no such advantages.
By extention of this, it's ludicrous to assume that Kreia, who has shown the ability to floor multiple Jedi masters without having to resort to her lightsaber, would be defenseless against Vader because he:
1. TKed a bunch of small objects in a straightforward manner at an untrained Luke.
2. He can rawr angry Hulk TK stuff at times.
3. He has a historic level of the Force which he clearly divorces himself from on some level, restricting himself except for his rawr hulk smash moments.
4. He has consistently demonstrated less knowledge of Sith techniques than most Sith, being instead handfed very little from Sidious over the years.
So yeah, aside from assumptions about his defense, assumptions about his Force connection, I don't see a building argument here.
(4) Vader is well-known for using the Force in many directions at once. In ESB, when his character was still being defined, he used the Force on several objects at once during his bombardment of Luke. In RotS, after refining the franchise's approach to the Force, GL authorized a passage wherein Anakin tosses several different objects at the Count with back-breaking speed. Against a foe that stands stationary as Kreia always has, these tactics will be devastating.
So? Kreia can fight with three sabers simultaneously while raining down abilities like aforementioned Force Drain, TK, Slow/Stun/Fear, etc. She doesn't run all over because she doesn't have to; she can literally rain hell on foes with abandon. Only Nihilus overcame her because his power and nature implies that he's cosmically powerful. His voice sparked a reaction in the Force which consumed all life on a planet and ravaged its surface, so I'm forgiving that Kreia lost to him in a direct Force contest but can level just about anyone else.
Hell, when she decides to, Sion becomes her ***** without argument. This is a guy who can't die.
Again, I disagree with the premise that the drain is instantaneous. If it is not, all he has to do is interrupt the attack, and suddenly Kreia is on the defensive.
How can you disagree with visible proof that it's instantaneous? She doesn't bring out spell components, sign in the air, or go blonde and yell "KAMEHAMEHA"... She just states "I'm going to make you see through the eyes of the Exile" and gestures, and an arc of beam equivalent to Sith Lightning kills them.
How is Vader going to be faster than that (which he hasn't demonstrated) or is going to defend against it?
Lastly, Kreia has demonstrated the ability to hide herself in the Force, even when within a few dozen feet of other Force users (the Jedi Masters, Visas, and Atris). Vader lost Luke Skywalker in a single room. Against a powerful Jedi Master turned Sith who can make herself unsenseable, who can level a powerful and potentially fatal/KOing ability at will, and who besides that can demonstrate Force powers much more varied and refined (Stun/Slow/Fear)... How does Vader "tank" or "Speed DPS" all this before he drops dead?
