I'm not saying "well Revan isn't the best", I'm saying that nothing Revan has done has distinguished him as the best.
I'll say this again, because you seem to have selective vision, no one in the KOTOR era(aside from Nihlius) has done anything on the level Revan has, He was able to toy with the minds of an entire species, create force storms, overpower planets steeped in the Dark Side, had the best Battle Precognition known to the galaxy. Name ONE person in KOTOR who has even come close to this.
You have no evidence to support your argument and you sound like an idiot since you keep saying the same things over and over. I'll ask you AGAIN why are Revans feats unimpressive compared to the other greats of the KOTOR era who you can't seem to name?
And what does near invincibility mean anyway? You're either invincible or you're not. Why bother mentioning that he's nearly invincible? Do we have a measure of what it is to be nearly invincible? C'mon it's quite clearly hyperbole, credit to Malak for putting up a fight but outside of the hyperbole it doesn't tell us how strong Malak was in comparison to Revan and vice versa.
The exact quote:
The Sith Lord had grotesquely adapted the Rakatan device to draw energy directly from chained Jedi captives. Malak was nearly unstoppable. - Star Wars Databank
I'll admit I got it wrong when it said invincible, but unstoppable is pretty much the same thing.
Since you asked for gameplay evidence of Malaks power, we can turn to the Wizards of Coasts article about him.
An imposing figure with ghostly pale features, prominent Sith tattoos, a gleaming red lightsaber, and devastating Dark Side power, Malak struck terror into the hearts of his former allies. He also wore a vocal mask that may have concealed a form of cybernetic life-support. Did it provide him with powers far greater than even Exar Kun or Freedon Nadd, or was cybernetic enhancement too simple an explanation?
Enhanced Force Powers -- Using a mysterious power source as yet undiscovered (complete Star Wars: Knights of the Old Republic to learn more), Darth Malak possesses extraordinary dark side Force powers out of proportion, in game terms, with his class and level.
And if were going by the D20 system Malaks in game powers and feats are off the charts:
Str 20, Dex 14, Con 16, Int 13, Wis 17, Cha 20.
Force Skills: Affect Mind +9, Control Mind +14, Battlemind +17, Enhance Ability +15, Fear +20, Force Defense +15, Force Grip +18, Force Lightning +24, Force Strike +11, Move Object +15, Telepathy +13.
Force Feats: Alter, Burst of Speed, Control, Drain Force*, Force Mind, Force Whirlwind, Hatred*, Knight Defense, Lightsaber Defense, Malevolent, Master Defense, Mettle, Rage*, Sense, Sith Sorcery*, Sith Sword Defense*.
Special Qualities: Damage Reduction 5 -- Darth Malak ignores the first five points of any kind of damage. Whether this is due to hidden armor linked to his voice mask or the physical result of Sith alchemy is anyone's guess.

Really Malak was no joke. Oh yeah BTW Revan beat that...twice.
And as concerns feat wars, your example is flawed in that your claiming one character is more powerful than the other based on a feat another character hasn't performed. It doesn't work that way, we determine the characters power by their most impressive feat, not who has done what specific feat.
Again selective vision, what are you talking about? Jacen and Revan performed pretty much the exact same feat, probing the mind for information.
I'll break it down for you.
Jacen attempted to do it to Boba Fetts daughter Ailyn Vel, accept with his lack of control and force mastery he accidentally caused and aneurysm and killed her.
Revan ripped a complex language system out of one of their heads, without killing them, then he shoved Galactic Basic inside their heads so they could understand him, also some of these Rataka were force sensitive. Now that level of force mastery is amazing.
Jacen the number 2 of the New Jedi Order couldn't touch Revans feat, so that alone means Revan is more powerful in the force then the entire NJO save for Luke.
What don't you get about this?
I appreciate that he didn't stick to one particular dogma, but that doesn't mean he used the dark side. Revan doesn't stick to any one ideal, but what do ideals have to with following the dark side? Ideals have little to do with the dark side and Revan quite clearly turned away from the dark side to follow the light, not the Jedi ideals specifically.
Again as I said it extends past dogma, to even affiliations to the force, hence why Revan had access to both Dark and Light powers, much like Jacen Solo.
