(Dynasty of Evil) Darth Bane -vs- (The Force Unleashed II) Darth Vader

Pretty much. In a way she is like a young Anakin, a shit ton of raw potential but not having the skill neccesary to wield it properly. In the end, Luke can fight her almost evenly.

What's really impressive is that Anakin defeated two Abeloth-level force users at once on Mortis.

I think she is 20 times more powerful because of the Psychosis, and her telepathy and mind domination.

No, her "force strength" is twenty time more powerful.

So she is like untrained TPM Anakin Skywalker almost?

Er, no. 20 times more powerful than his full potential in raw power, apparently.

Luke=Full Potential Anakin.

Abeloth>Luke.
Abeloth>Anakin.

Granted, I have not kept up with FotJ due to lack of funds to buy the books, but I had still assumed it was due to knowledge or such. You guys know how "Force Strength" works, especially how everybody and their mother is Strong in the Force.

TPM!Anakin doesn't accidentally disintegrate cities populated by [hundreds? thousands?] of Sith Lords. Or, in other words:

Luke is only said to become what Anakin could have been, which is more powerful than the Emperor. Nowhere it is explicitly said that their potential is identical. If anything, Anakin's role as the prophesied Chosen One suggests that this is not the case. Or, in other words:

Retconning Abeloth as a servant of the Ones who dominated the Son and Daughter but fled before the Father is a potential snafu, since Anakin cowed the Son and Daughter on Mortis and was intended to replace the Father, suggesting parity (or, rather, potential parity) between Anakin and the Father, in turn suggesting that the distance between Abeloth and Anakin [in terms of Force strength/potential] is not severe.

But that's just speculation.

That we know of... Who knows what kind of stuff he did when he was a baby even. Someone actually posted a theory at official forums one time that maybe all the unexplained disasters that occur in SW is result of accidental use of Force from untrained force sensitive babies...

In all fairness - Luke had to manipulate a Dovin Basal to create and control Black Holes.

Luke can't create or control one by himself.

Vader's prime would be ESB and ROTJ, while pre-ANH Vader isn't fully near his prime. Anyways, I go with Bane both rounds.
Round 1: Bane wins with some difficulty.
Round 2: Bane owns him, Vader has no capable answer for the Orbalisk Armor.
If this was ROTJ or ESB Bane Round 1 might be harder for Bane to win, but he still wins
