Plagueis is the most powerful force-user with the second being Darth Sidious and the third being Yoda. Darth Plagueis created Anakin Skywalker through meditation, and trained Sidious in the dark side using quite a few new methods. He created new ways to use the Force that others had never even thought of.
Emperor Palpatine/Darth Sidious
At his most powerful, Sidious was able to not only create life from nothing, but was able to create a prophecy-fulfilling Chosen One by manipulating the midi-chlorians to create Anakin Skywalker, who was himself one of the most powerful beings in the galaxy.
If you're talking about Anakin at the end of the Clone Wars and Luke at the end of Return of the Jedi, then Anakin wins hands down. That is Anakin in his prime. His mastery of the Force was exquisite, his lightsaber technique impeccable.
In Star Wars Legends and Canon, Galen Marek (Starkiller) is the only Jedi (other than Obi-Wan Kenobi) to put a beat down on Darth Vader/Anakin Skywalker.
Aside from agility and telekinesis, Yoda could absorb and redirect Force attacks, like lightning. Because of his higher understanding, he would easily overcome Darth Vader in a fight, though that doesn't mean it wouldn't be a difficult battle.
In the Star Wars: The Force Unleashed video game, Darth Vader dispatches Starkiller to kill a number of Jedi who have survived the Great Jedi Purge. Starkiller is initially kept in secret, but he is discovered by Emperor Palpatine, he is seemingly betrayed and killed by Vader.
One of the main reasons why Yoda would've won against Anakin is simply because he was far better trained than him. Yoda could see the moves his opponents were going to make before they made them; therefore, battling against Anakin would've put him at a far heavier advantage.
Though there was some debate among the fans that Anakin Skywalker's son, Luke Skywalker, was actually the Chosen One since he caused his father to destroy Darth Sidious, the debate was settled when George Lucas himself confirmed in an interview that Anakin, even after becoming Darth Vader, was still officially the ...
Leia was not using the Force or was currently Force-sensitive during her confrontation with Vader. She began training as a Jedi years later. All these reasons prove my point: Vader didn't know Leia was his daughter, and felt no presence of the Force in her, as she was not currently strong with the Force.
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%.
Biography. Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo.
1 Darth Vader - Hundreds
During his time as Darth Vader, the powerful Force-user continued to hunt down Jedi, devoting himself to the Order's extinction until he became aware of his son's existence.
Arguably, some of the rarest types of Jedi were the so-called Iron Knights. These are members of the Shards species - crystals with a brain of their own. They were Force-sensitive and all trained under the tutelage of Jedi Master Aqinos. The Shards had droid bodies, similar to that of General Grievous.
Plo Koon. Wise and compassionate, Plo Koon was one of the most effective Jedi masters, genuinely caring about the clones he commanded.
The Jedi from the Star Wars prequels, including Master Yoda, did not understand Anakin Skywalker's Chosen One prophecy for these essential reasons. The Jedi of the Star Wars prequel era clearly did not understand the famous Chosen One prophecy.
Over the years, Luke Skywalker and Darth Vader encountered each other a number of times, with Vader getting the upper hand nearly every time. However, once Luke fully embraced his power in Star Wars: Return of the Jedi, he proved that he was indeed stronger than Darth Vader and struck his father down.
History. Before he became a disciple of the dark side, Darth Vader was Anakin Skywalker, a goodhearted Jedi and hero of the Clone Wars. While he was considered one of the most powerful Jedi in the galaxy, Anakin had broken the Order's code by secretly marrying Senator Padmé Amidala.
More cunning and devious than all but the most attuned Force-sensitive beings, Darth Bane could more than likely defeat Yoda in a battle of both strength and wit.
By the time of Episode 3; Anakin is in his prime, and already one of the Jedi Order's most powerful “masters” (although technically still a knight), just behind Obi-Wan, Windu, and Yoda. Maul wouldn't stand a chance. Anakin stomps.
1 Darth Sidious
There has been no Sith, as powerful, meticulous, nor as evil as the Emperor himself, Darth Sidious. As previously mentioned, Sidious trained in the Dark Side by Darth Plagueis before Sidious killed Plagueis in his sleep, making Sidious a Sith Master.
A Sith in all but name, Starkiller spent years honing his skills in lightsaber combat and Force techniques as Vader's secret apprentice and personal assassin.
Pinned beneath Starkiller with his lightsaber at Luke's throat, he was forced to hear the truth: that Vader was his father...and that Starkiller was the one who murdered him. Enraged by this, Luke hurled Starkiller across the hangar and unleashed the Dark Side on him.
