Qui-Gon Jinn was a respected, independent Jedi Master who first located and identified Anakin Skywalker as the Chosen One foretold in the Jedi Prophecy. Born on Coruscant circa 80 BBY (Before the Battle of Yavin), Qui-Gon trained as a Padawan under Jedi Master
Within the first six months after his birth, Jinn was identified as a Force-sensitive and was taken from his homeworld to the galactic capital of Coruscant to train at the Jedi Temple and become a Jedi.

Yoda came to discover that Qui-Gon had discovered the secret of surviving beyond the grave. In his travels, Qui-Gon had learned much from a Shaman of the Whills, who taught Qui-Gon that a path to spiritual survival required absolute selflessness. Qui-Gon taught these ways to Obi-Wan and Yoda.
Over the next decade, the galaxy was on the verge of civil war with entire star systems—led by Count Dooku, Yoda's one-time Padawan—threatening to secede from the Republic by 22 BBY.
Padawan Windu was trained in the ways of the Force by Jedi Master Cyslin Myr.
Why Qui-Gon Jinn Was Palpatine's Greatest Threat. Unlike Yoda and the Jedi High Council, Qui-Gon Jinn was only concerned about the will of the Force. Therefore, Palpatine needed Qui-Gonn out of the way because he was better connected to the Force than the other Jedi.
Because the truth is, Qui-Gon Jinn was a unique Jedi, one who stood on the fringes of the Order and yet had enough influence to potentially disrupt all of Palpatine's plans. Truly the dark side favored Palpatine when Maul succeeded in killing Master Qui-Gon Jinn.
Sidious, born Sheev Palpatine, was trained in the dark side of the Force by Darth Plagueis.
He can't call out to Qui-Gon Jinn because he has barely retained a connection with the Cosmic Force. It's why his mind is plagued by the kind of images and voices that drove Anakin to the Dark Side. Obi-Wan has lost his way in much the same way Luke Skywalker will one day.
Master Yoda has risen above all others to claim the top spot as the most powerful Jedi of all time and the true chosen one according to IGN's audience. He won pretty handily as well, as he was victorious in 89,756 of his 95,243 battles and had a win percentage of 94.2%.

Palpatine admits to Darth Vader that the Jedi he actually feared most was none other than Jocasta Nu.
We are just barely seeing a 600-something-year-old Yoda in the High Republic era. And given that Qui-Gon Jinn dies in 32 BBY, a fight beyond that point would be pointless since, as a Jedi spirit, Jinn would arguably be stronger than the still physically alive Yoda.
It was Qui Gon who knew that the Jedi Council were self absorbed and blind. It was Qui Gon who had to teach Yoda about becoming a force ghost. Basically both of these things show that Qui Gon was actually the wise one, not Yoda.
Mace Windu failed in his mission to arrest Palpatine in Star Wars: Episode III - Revenge of the Sith, but Yoda may well have fared better. As powerful as Darth Sidious may have been, it's easy to forget he actually seemed afraid of Master Yoda.
Before the Fall of the Republic, Jedi Master Qui-Gon Jinn learned the ability to become a Force spirit from the Shaman of the Whills, but was killed by Darth Maul before he could complete his training.
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.
