When it comes to pure skill, Levi far outranks Eren. Not only does Levi have more experience in the field, but he's also just a better fighter overall. Without his ability to transform into a Titan on command, Eren wouldn't stand a chance against Levi.
Levi will get destroyed by Eren in human form.
He was a completely incompetent human combatant and remains an abysmal ODM user (having only defeated two titans directly outside of his enhanced form, one of which was due to Armin's distraction).
No, Levi Ackerman is stronger than Mikasa Ackerman and Mikasa is stronger than Eren.
Zeke, the inheritor of the Beast Titan, is Levi's greatest enemy. The two have fought in many epic battles throughout the series and are very close in strength.
1 Levi Ackerman
He's arguably the best Ackerman in the anime. Levi's abilities allow him to excel in fighting not just titans but also human enemies. He's also the only non-titan character in the anime to take down a Shifter Titan single-handedly as was shown when he defeated Zeke in Beast Titan form.

1 Goku (Dragon Ball)
Even with all of his strength, there are still a few characters that Goku cannot defeat, and Eren is nowhere near their level. After years of training, Goku can now use Ultra Instinct, a special transformation that puts him at the same level as a god.
And the idea of Levi hating Eren, well, that is not so evident— but with some analysis, one can speculate that he "disliked" Eren at best, due to his initial suspicion of him. Levi has also called Eren a monster on multiple occasions due to his uncontrollable nature and strength.
Eren attempts to strike at the Colossal Titan's nape, but Bertholdt makes use of his steam emission control and prevents Eren from getting close. As Eren fights against Bertholdt's steam and comes in for the killing blow, the Colossal Titan vanishes instantaneously.
1) Thor. Regardless of the form Attack on Titan's protagonist takes, Thor Odinson can easily defeat him. Despite being in Attack or Warhammer form, Thor can easily call lightning down to the nape of the Titans, eliminating the form and Eren in the process.
Zeke is more powerful than Eren while Eren is stronger than Zeke. Zeke has a royal blood while Eren doesn't. Zeke can turn humans into pure titans and he can control them since he has a royal blood while Eren currently holds three titan powers.
Founding Titan is the first and the strongest Titan of all the nine. If the Founding Titan is someone from Royal Bloodline, then it will possess limitless power. Eren Yeager was not someone of royal blood that's why he asked for Zeke's help to use the Founding Titan to its fullest.
The Colossal Titan is one of the most powerful creatures on Attack on Titan. Standing at least 50 meters high, they can lay waste to anything and everything in their path. The only thing that can beat them in either height or power is the Founding Titan -- and even that's somewhat debatable.
Unsurprisingly, Levi Ackerman ranks #1 on our list. He's the best Titan killer, flying through the air on his ODM gear like he was born in it.
Eren was beat up by Levi in court because of the fact that they, Survey Corps needed to show that they can control Eren and his abilities, and therefore take legal custody of him.
While there are many characters that he respects, Erwin Smith is perhaps the only character that Captain Levi has truly loved, which puts Erwin at the very top of the list. Levi's loyalty and devotion to Erwin also indicate that the two were meant to be together.
Levi was one of the few characters never to have been intimidated by any of these goliaths even early into his career under the watch of Erwin Smith. Instead, his only fear is of the potential loss of his comrades, especially in his first missions.
After being kidnapped in her youth by bandits and subsequently rescued by Eren, Mikasa has pledged her life to her companion. Similarly, she protects Armin from street bullies. Because of this pledge, she is physically stronger than both the boys and is constantly beating up their enemies.
Apart from the Eldian Titan Shifters, Eren has always had a long-standing rivalry with one of his comrades, Jean Kirschtein.
The soldiers concluded that, in order to halt the Rumbling, they must kill Eren Yeager by any means necessary. Returning to Eren's Titan, the allies launched their own counterattack on the Titans.
1 Winner: Eren
Eren will regenerate from most of them. Unless Midoriya figures out Eren's weakness and hit him with 100% One For All in the nape. Once Midoriya gets exhausted and slow.
1 Eren Yeager
The protagonist of the story, that resorted to mass genocide to protect the things he loves, is at the top of the list. Before he decided to do that, he had been killing titans as a titan shifter of the Attack Titan.
After a 25-minute standoff two of the police officers, Constable Rodney Podesta and Senior Constable Anthony Dilorenzo, shot Roni Levi four times. Levi, who died from his wounds soon after, was 33 years old.
The show has also charted Mikasa's journey of living for herself and not just to protect Eren as in earlier seasons, and she's proven to be a formidable fighter. This includes the fact Mikasa has killed 16 Titans thus far, according to CBR.
