well, before i can answer, you should specify where the battle takes place. Qui-Gon is a master of ataru, a fast and agile combat style. The main reason he lost on tatooine was because he needed to stay near the ship, and the sandstorm prevented him from using his full technique. Plus, if they had a chance to use the force, maul would get wiped out. However, Maul would be an excellent comabatant for him in an even battlefield, but you probably just cannot fin d one. It goes one way or the other easily here, it all depends on location.
