From simple google searches you can find that Yoda's midi count was 18,000 per cell, Obi-wan's was 15,000, Palpatine's is said to be higher that Yoda's around 18,500-19,000, and the highest known was Anakin Skywalker's at 20,000 midis per cell.
The Jedi however also have three outliers in that of Luke, Leia, and Cade Skywalker (23000/23000/21000 midi-chlorians respectively) all of which were children/descendants of Anakin Skywalker (the chosen one) and so genetically predisposed to having abnormally-high midi-chlorian counts for Jedi.
Midi-chlorian counts were linked to potential in the Force, ranging from normal Human levels of 2,500 per cell to the much higher levels of Jedi. The highest known midi-chlorian count—over 20,000 per cell—belonged to the Jedi Anakin Skywalker, who was believed to have been conceived by the midi-chlorians.
In Legends, Obi-Wan's midichlorian count was around 15,000. Yoda's was around 18,000, and Palpatine's is estimated to be just higher than Yoda's so let's say it's between 18,500 and 19,000.
Obi-Wan Kenobi is actually a great example of a Jedi with this level of midi-chlorian density. He had a midi-chlorian count estimated to be about 13,000. While this is a lot, it's definitely not as much as other Jedi.
The reason why Anakin's Midi-chlorian count is the highest is also the reason why the Skywalker bloodline is so important in the Star Wars saga. In a scene that was cut from Revenge of the Sith, Palpatine explained to Anakin that he manipulated the Midi-chlorians in his mother's womb to create the perfect apprentice.
However his midichlorian COUNT was unchanged. Midichlorian counts, in the way they determine force sensitivity, are based on cellular concentration. Short of altering one's DNA that concentration cannot be changed. So Vader's midichlorian count never diminished.
Darth Vader's midichlorian count was at least above 20,000 per cell. It was probably at least 27,000.
It's talking about pregnant Padme, who has the Luke and Leia inside her. She has the midichlorians of two powerful Skywalkers inside her at that point. 2 Skywalkers are better than one, so Padme has more than even Anakin.
In Luke Skywalker's confrontation with Palpatine during The Return of the Jedi, he tells the Emperor that his overconfidence is his weakness. That turns out to be true as Palpatine takes too long trying to kill the young Jedi, which gives Darth Vader...
The general rule of a Force dyad is it can only exist with a light and a dark side. Kylo Ren and Rey are another example of a Force dyad. It is said, in a Force dyad, that the powers mirror and amplify one another, which could indicate that Grogu is at the very least of equal strength to Anakin Skywalker.
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%.
Anakin Skywalker is the son of Shmi Skywalker, born without a father through the Force. He is the secret husband of Padmé Amidala, the father of Luke Skywalker and Leia Organa, the father-in-law of Han Solo, and the maternal grandfather of Ben Solo.
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 ...
We know from the dialogue that no one in the Jedi Order has a higher midichlorian count recorded then that of the blood sample of young Anakin taken by Qui-gon and analyzed by Obi-Wan. So this infers that Anakin has the highest count ever recorded followed by Yoda (he seems to be a distant second).
Even though Leia was rather advanced for her age, having learned to speak and walk before the age of one, she did not show any signs of Force potential—much to the relief of her adoptive father, who knew that being a Force-sensitive in Palpatine's Empire would be a heavy burden.
There are a lot of hints given throughout the Star Wars franchise that Padmé Amidala was in fact Force sensitive. It is clear that the young queen and later senator from Naboo was not strong in the Force or trained in the ways of the Jedi, but she very likely still had some low-level sensitivity.
Obi-wan's midichlorian count was 15,000, Obi-ike's was 18,000, and Palpatine's was higher, which is estimated to be around 18,500 to 19,000. Anakin Skywalker was the most well-known figure, with 20,000 midis per cell.
Because his body had been severely burned on Mustafar, Darth Vader was thought to have lost much of his Force potential, although he nonetheless retained an incredibly high midi-chlorian count.
As a young Jedi Knight, Anakin lost a hand in a battle with Count Dooku, which received a robotic replacement. He later returned the favor by removing both of Dooku's hands. Eventually, he lost both his legs and his remaining arm in the climactic duel on Mustafar between both he and Obi-Wan.
It was also the foundation of life, with all life forms serving a symbiotic host for the living organisms native to the wellspring. In modern science these intelligent microbes became known as "midi-chlorians." The existence of midi-chlorians was known to both the Jedi and the Sith.
Strongest: Canonically the strongest Sith Lord in history was none other than Darth Vader. Darth Vader had the highest force potential in Sith history. He never reached that potential but still achieved a level of power unprecedented to all before him.
Palpatine himself also possessed this power to a limited degree, having participated with Darth Plagueis in the aforementioned experiment that ultimately resulted in Anakin's conception.
