Yeah, if the power of the force was distributed to an alignment's number of members, then there's no way anyone on the lightside should be able to rival Sidious or Dooku and yet, multiple people do(Yoda, Jedi Anakin, Mace ect.)
Plagueis himself admitted they'd get wrecked by the jedi order if they took them head on which shouldn't be the case if power was equally distributed to the members of each alignment.
That's because Rebels Kenobi suckered Maul in with Qui-Gon's stance, and Maul used the same move to defeat him that he used against Qui-Gon.
We've been explained that by both the Rebels Recon on the episode and by Witwer. So no point in disputing it.
I don't know where you're getting that it was such a hard fight for Maul. He got caught off guard once, but still defeated him, and it didn't take much longer than the time it took to defeat Qui-Gon (both on Naboo and on Tatooine).
You have Ventress disarming Kenobi in TCW movie, yet Kenobi goes on to stomp her. Savage disarms Dooku, yet Dooku still manages to fight off him and Ventress.
Being disarmed of part or all of your weapon isn't the end of the world.
No Enraged TPM Kenobi wasn't on Dooku or Windu level, but then TPM Maul wouldn't defeat Dooku or Windu in 35 seconds either. Maul force pushing Kenobi down the shaft was showing Maul being the superior duelist/combatant. Because Kenobi didn't anticipate and try to block it.
Now if Kenobi attempted to block the Force push and still got overpowered (like Anakin vs Dooku in TCW movie), then you could argue Kenobi matched Maul with a blade but Maul only won due to superior TK. But that's not how it happened. If not a Force push, it would have been a punch or a kick, but either way Kenobi was going to get defeated in direct combat, because he simply wasn't on par with Maul as a combatant at the time.
Is it plausible that Qui Gon had a potential on the level of Dooku?
I mean, as per the Core Rulebook, Yoda considered Qui Gon as a youngling to be better than Dooku( the best student he had trained in over 400 years in the Order and this fits in what we know about Yoda which is that he gave up the training of apprentices somewhere in the middle and began training younglings in the Jedi fundamentals to prepare them for their journey as a padawan). Additionally, Dooku also gives Qui Gon some pretty excellent hype and holds him in pretty high regard.
Given that TPM Maul's position is more or less on the same level( whether he is above or below Dooku is up for interpretation) as TPM Dooku's and that Qui Gon was pretty competent against Maul, it kind of fits what we know about them.
TPM Dooku's "exact" position also seems to be wavering below TPM Maul's position, so we can easily deduce that Qui Gon is reasonably close to TPM Dooku. In addition, there is a gap of 10 years between them. Could Qui Gon bridge that gap in that much time?
As for "exhaustion" which is likely to be a counterargument, firstly, we don't know how well Dooku who is infinitely weaker than ROTS Dooku would fare against an enemy like Maul and secondly, Qui Gon uses a form that is the most likely to exhaust someone of his age, while Dooku uses a form that is "least" likely to exhaust someone of his age, which is a pretty big factor to consider.
At least, this is how it looks like, which is my interpretation. It may not be the case. Thoughts on the matter?
I always took that to mean that QGJ had a better understanding of the Force that mirrored and/or surpassed that of Dooku and (possibly) Yoda due to the whole force ghost spiel, not necessarily combat prowess.
*shrug. Regardless, you may or not be right. as in Legacy of the Jedi? I think it's what it is called. I think there's a quote calling Padawan!Jinn an equal to Jedi!Dooku so *shrug
