"Lucas claims that, as a masked and suited Darth Vader, Anakin has roughly 80% the strength of the Emperor. Had he sustained none of his injuries on Mustafar, he would have been about twice as powerful."
That's from wikipedia. Both things are taken from an interview with Lucas but I can't remember where that was. Well Lucas at least contraticted that statement ones saying "Anakin had the potential to become 10 times as strong as Sidious".
Now for gods sake Anakin could be 200-1000 % of Sidious while NJO Luke could be 150-750 % Sidious. And basicaly that says nothing because we don't know what "powerful like Sidious" does mean compared to the ancient Sith lords.
And since I get bored pretty much here is my own suggestion:
Actualy we should make differences between 3 terms:
a) force potential
b) force powers
c) power
Force potential is the sheer amount of midichlorians that somebody has. It is very safe to assume that Anakin Skywalker exceeds everybody in that followed by Luke Skywalker, Anakin Solo, Jacen and Jaina Solo and Ben Skywalker.
Force power is another thing. You can be more powerful than somebody who has a higher potential just because of being more experienced or having learned more. This can be seen for example in duel between Obi-Wan and Anakin in ROTS. Anakin has clearly more potential than Obi-Wan but as they try to force push away eachother they are equal.
The term "power" referes to any other abilities that are important in combat. That actualy means lightsaber skill and things like Sith magic, artifacts, special lightsabers or unique force powers (Moricho) or things that can't be learned (Nihilus eating ability, Mace Shatterpoint ability).
Back to the topic:
Grant all of the NSO at least the knowledge that Sidious had (force lightning, force storms, jedi knowledge and so on).
Now Anakin Skywalker fully developed is a damn nightmare. What do you think will happen if he unleashes force lightning that is twice as powerful as that of Sidious on Ragnos. Hey...he is at least 25 % more powerful than NJO Luke. Run for your lifes.
A dark side Yoda could waste Sidious in the blink of an eye. That's what Dooku thinks about it. Just imagine Yoda being an offensive bad ass where he is pretty much defensive in the films. The dark side gave Luke enough power to overwhelm Vader. Imagine Yoda giving into his anger...Naga Sadow is toast.
Mace entered the Jedi Council being 28 years old. That is an age where people like Revan or the Exile just have become Jedi Knights. He has to be realy powerful. Now think of him having studied Sith teachings for all his life (53 years) he would clearly be more powerful than Dooku maybe as powerful as Sidious but still and still a major bad ass when it comes to lightsaber combat. He might take Revan.
And Obi-Wan ? Well...did you ever see a Sith Lord using a defensive lightsaber style ? He could probably fend people with one hand and force lightning them with the other. Still he would have a hard time against Exar but maybe win. I don't know.
I agree that Obi-Wan and Mace are the "weak links" in this fight but Yoda and Anakin would be quite amazing. So even if Revan and Exar come out of their fights alive, Yoda and Anakin will destroy them.
