The reason why Qui-Gon Jinn is the most powerful Jedi in the galaxy is because he had seen everything that would unfold throughout the Skywalker Saga in a vision of the future, sacrificing himself to ensure the fulfilling of the Chosen One prophecy.
A venerable if maverick Jedi Master, Qui-Gon Jinn was a student of the living Force. Qui-Gon lived for the moment, espousing a philosophy of "feel, don't think -- use your instincts." On Tatooine, Qui-Gon discovered a young slave boy named Anakin Skywalker who was strong in the Force.
Qui-Gon is one of the most powerful Jedi in the saga: highly skilled in the Force and mastering abilities that other Jedi couldn't, including the ability to consciously manifest after death. But more than his abilities as an individual, it was his maverick philosophy that the Emperor feared.
After Qui-Gon was killed by Darth Maul, Yoda was saddened, but continued to disapprove of Qui-Gon's unorthodox ways, regarding them as "defiance". After he failed to defeat the Emperor, Qui-Gon's spirit taught Yoda the Shaman of the Willis.

What did Vader think of Qui-Gon?
Qui-Gon Jinn: the One Jedi of Value
Master Qui-Gon Jinn's words echo in Vader's mind. There's no anger, nor hatred in this memory – Vader simply recalls one of the first lessons the Jedi Master slyly gave to young Anakin Skywalker.
Qui-Gon was Dooku's apprentice. Dooku loved Qui-Gon like a son due to their many similarities; both were individualists, idealists, and both had knowledge of the Force that was unique.
The part about being born of no father is what ultimately convinced Qui-Gon that Anakin was the Chosen One, because Anakin's mother Shmi Skywalker had told Qui-Gon that Anakin was born through immaculate conception.
Qui-Gon Jinn was far from a powerful Jedi Master when it came to fighting. He couldn't even defeat a single Sith Lord's apprentice. He was also the Jedi Master who put too much trust in Anakin Skywalker as his apprentice, which was a proven disaster.
Because Maul punched him with the hilt of his saber and then stabs him faster than Qui-Gon can pull back his blade. So Qui-Gon lost because Maul was physically stronger and quicker than him. Qui-Gon is skilled but not a prodigy. And he's quickly worn down by Maul in both their encounters.
What would have happened if Qui-Gon Jinn survived?
Dooku, AND Anakin, would be less likely to fall to the dark side if Qui-Gon was left alive and Maul's sympathetic past would never be revealed. For the former, Order 66 wouldn't be executed since Dooku wouldn't be the one planning to do that on the clones.
In 60 BBY, Jedi Padawan Qui-Gon Jinn fell in love with an individual on the Outer Rim planet Felucia. He eventually broke off their romantic relationship to remain in the Jedi Order but nevertheless kept their gift to him—a Mustafar fire diamond—as a cherished memento for many years.
We are led to assume this as in TCW Qui-gon admits his training was incomplete. He could only appear on Mortis, anywhere else he could only be a disembodied voice.
Summary. Qui-Gon saw potential in young Anakin Skywalker as the Chosen One, and could have prevented his dark fate. Marvel's new Phantom Menace Special issue further confirms Anakin needed Qui-Gon's guidance to control his emotions and remain on his Jedi path.
He was a wise and well-respected member of the Jedi Order, and was offered a seat on the Jedi Council, but chose to reject and follow his own path. Adhering to a philosophy centered around the Living Force, Jinn strove to follow the will of the Force even when his actions conflicted with the wishes of the High Council.
The Chosen One was revealed to be Anakin Skywalker, who conceived by the Force itself via the mystical one-celled organisms called midi-chlorians completely without outside influence.
He was not so content to blindly follow the Republic. and was more sensitive to the will of the Force. Qui gon represented the ideal Jedi, and had he been able to sway others within the Order, it could have presented problems for Palpatine.
Star Wars has many love stories; one of my favorites is between Qui-Gon Jinn & his betrothed, Jedi Knight Tahl. It was told & developed so well. [Jedi Apprentice series]
Dooku as a Jedi Knight with Padawan Qui-Gon Jinn, and Jedi Masters Yoda and Tyvokka. Dooku became a Jedi Knight in his early twenties and took Qui-Gon Jinn as his first Padawan. The two were quite close in age, with only ten years separating them. When only ten, Jinn had impressed Dooku with his potential.
Qui-Gon Jinn, who is considered a maverick Jedi Master by his colleagues, might have been able to keep Anakin on the path of the Jedi, had he not been killed by Darth Maul. Star Wars' Qui-Gon Jinn would have been the ideal mentor for the young Anakin.
