Darth Revan was consistently in the top tier of Jedi and Sith from his time. From fighting an entire strike team of accomplished Jedi, to defeating SF Malak (an opponent superior to Exar Kun), to presenting a challenge to Darth Vitiate himself, Revan's feats are nothing to scoff at, even long before his prime.
Even at an early age, Revan's insatiable hunger for knowledge and mastery over the Jedi arts drove him to be the Order's most powerful champion against the Mandalorian threat.
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%.
In Legends, Revan was a Jedi Knight who broke away from the Jedi Order, became a Dark Lord of the Sith, and formed a Sith Empire that waged war against the Order and the Galactic Republic.
1 Darth Vitiate
Known as the Sith Emperor, Vitiate was not known for his proficiency with a lightsaber – though as a Sith he was very well versed in combat and could hold his own against the most skilled warrior – but instead for his absolute mastery and control of the force itself.
As impressive as Vader's battle tactics might be, if he and Revan make a stand with comparable armies, Revan is likely to be victorious.
Revan triumphs in this contest mostly through statistics. He was the greatest warrior of his time, while Anakin was not. Also, Revan could interfere with cosmic bodies like meteors through his Force powers. Vader never achieved such feats.
In the areas of a tactical skill, light saber ability, and force power, Revan is vastly more skilled than Kylo Ren. He wins easily. He can take Revan down with his force abilities without relying on his lightsaber, but with his lightsaber, he could take down Kylo Ren in one minute tops.
That person was Darth Traya, or as she was once known, Kreia. Kreia's story begins with Revan's, teaching him in the ways of the Jedi. Long had she forsaken her eyesight and taught her students more in mental skills. She used her spare time to learn more about the deeper mysteries of the Force.
Revan is extremely powerful in the ways of the Force, masterful in combat with a lightsaber. He possesses high agility, speed, and strength boosted by the Force that he uses in his fighting style. Revan mostly uses one lightsaber, but wields two as dark Revan, both his red Sith one and his original purple one.
But one Jedi stands above the rest and needs to start getting recognized as the greatest Jedi who ever lived. That is none other than Obi-Wan Kenobi. While this saga is ultimately the story of the Skywalkers, Obi-Wan is arguably the best and most pure Jedi to ever come out of it.
Darth Revan is pretty much Rey's superior in every way. His Force powers are greater, his lightsaber skills are vastly superior, and he's defeated some of the most formidable warriors in the galaxy.
Darth Revan
Many have described him as being the most powerful Force User of all time, making him superior to even Luke Skywalker and Yoda. Darth Revan had the ability to wield the powers of both the light side and dark side of the Force.
Revan has very good stamina but just doesn't have the power to beat Sidious, unless he could get him of guard somehow.
A Human male, the individual later known as Revan was born in approximately 3994 BBY, and some believed that he had been born in the Outer Rim Territories. The child who would be remembered as Revan was eventually discovered to be Force-sensitive and was accepted into the Jedi Order.
Tenebrae—known to the Old Sith Empire as Darth Vitiate, his reconstituted Sith Empire as the Sith Emperor, and his Eternal Empire as the Immortal Emperor, Valkorion—was an ancient dark-side entity of enormous power who manipulated galactic affairs for nearly 1,500 years.
Intense fight but Yoda would prevail. It's easy to underestimate just how good Yoda really is since he has had so few chances to shine in the movies.
Yoda is both the superior lightsaber duelist and Force wielder by a considerable margin.
Revan was not only a fierce duelist but was extremely strong in the force. Even though he was captured by Darth Vitiate, Revan was still able to exert influence over the Emperor and then destroy the Republic. He was one of the most feared Siths of his time.
Balance of the Force: As a being who has experienced the natures of both the Dark and Light Sides of the Force; Revan is capable of summoning and producing Force energy intertwined between both aspects that can incapacitate his enemies with it.
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.
Yoda was a legendary member of the Jedi Council as a Grand Master of the Jedi Order and member of a mysterious species capable of living for centuries. He was stronger than most in a connection to the Force and though he was small in size, he'd been so powerful and wise having had trained Jedi for several centuries.
