Qui-Gon vs Maul is kind of the opposite of AotC Anakin vs Dooku, in that sources initially portrayed Anakin as genuinely challenging Dooku but moved to Dooku stomping him. In the case of the former, earlier sources suggested that Maul was humiliating Qui-Gon but more recent sources have them as near-equals in combat skill.
That's basically my reason. Somebody who's that close to Maul in skill would beat Draco decisively, IMO.
Force is mostly up to personal interpretation since I don't believe either combatant has ever been portrayed as using anything close to maximum effort for Force feats. Qui-Gon just holistically seems to be more powerful, I guess.
They probably didn't read the text then. Maul had to ramp up his attack like 3 times because he couldn't break Anoon's defense. They actually dueled a fair amount of time, and it only ended so abruptly because of the location of the duel. Anoon had no space to give ground on top of the speeder so Maul eventually could've pummeled him into submission. Realizing that Anoon chose to try and take Maul with him by going allahu akbar. On neutral ground it would've been a long ass fight.
