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.
Both Jedi Master Yaddle, and now Grogu hold great force powers, but no Jedi Master has ever held greater power than Jedi Master Yoda. Throughout Star Wars canon, Yoda has shown off some incredibly impressive abilities.
Anakin Skywalker was stronger in the Force and more gifted than most of his peers. If there was ever a knock against him, it's that he could not give up attachment… something that drove him to the Dark Side. That aside, there's no denying his place as one of the greatest Jedi in Star Wars.
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.
Qui-Gon Jinn learned to manifest as a Force ghost after death, thus allowing him to retain his consciousness in the Force. Several other Jedi also achieved the same ability, most notably Obi-Wan Kenobi, Yoda and the redeemed Anakin Skywalker.
Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo. A Force-sensitive Hysalrian, N'Kata Del Gormo was trained in the ways of the Force and achieved the rank of Master within the Jedi Order.
Obi-Wan Kenobi
As a Jedi, his loyalty has no bounds. He is willing to do whatever it takes to ensure that his mission is complete and Luke is safe. When he dies, he continues to guide Luke as a spirit, showing that his loyalty remains true even years after his death.
George Lucas himself has stated that Anakin is the Chosen One and that the prophecy is true, although it had been misinterpreted by the entire Jedi Order. Lucas believes that both the dark side—greed— and the light side—compassion—are integral parts of human beings.
Though Yoda was extremely powerful in his own right, Luke, in bringing an end to the Emperor's reign, was able to accomplish what his master never could. Yoda faces off against Darth Sidious in Revenge of the Sith, but isn't able to accomplish his mission.
Nearly all the surviving Jedi Knights were hunted down and killed by Darth Vader, while Order 66 remained in effect indefinitely among the ranks of the Galactic Empire's newly christened stormtroopers. Masters Kenobi and Yoda, like many others, chose to go into exile, on Tatooine and Dagobah respectively.
According to Star Wars Legends content, the first Sith was a former Jedi Master, Ajunta Pall, who became a so-called Dark Jedi, or “Fallen” Jedi.
Yoda. Yoda was a wise, experienced, and powerful Grand Master of the Jedi of an unknown species and the oldest known prophet in existence (having lived at least 900 years), considered the wisest and most powerful Jedi Master within the Star Wars universe.

Vernestra Rwoh was a Mirialan female Jedi Knight alive during the High Republic Era. She was also occasionally nicknamed "Vern," although she disliked it. The former Padawan of Jedi Master Stellan Gios, she was promoted to the rank of Knight at the age of fifteen, making her the youngest Jedi to...
In The Art of Star Wars: The Rise of Skywalker, art director Rick Carter expressed his opinion that Rey was the one who fulfilled the prophecy rather than Anakin, stating that while that one would be a Skywalker, it didn't necessarily need to be one by blood.
Yoda will most likely win in a fight against Darth Vader because he is more skilled with a lightsaber and has the experience and feats that allow him to trim whatever size and strength advantage Darth Vader has over him. In fact, Yoda nearly defeated Palpatine, something that Vader could never do.
Yoda claims to have been training Jedi for 800 years. The second time Yoda mentions his long life is in Return of the Jedi, when he tells Luke, “When you reach 900 years old, you will not look as good as you will.” If we take Yoda at his word, that means the Jedi Master died at the ripe old age of 900.
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. Galen was secretly trained as a Sith Lord apprentice to Vader, but returned to the light side and the Jedi.
For Now - Luke Skywalker. In Legends, Luke Skywalker was the undisputed most powerful Jedi to have ever lived in our knowledge, surpassing Yoda.
