Let's see how powerful he was in the time of AotC and RotS.

Disarms two mercenaries with the Force.

Kenobi uses the Force to knock down giant trees that larger than a space shuttle in Felucia.

--- The Clone Wars Magazine #017 - Downhill (2013) - Timeline: 21 BBY

Kenobi uses a powerful Force push that cracks Asajj Ventress' ribs.

"Okay, Ventress, are you going to gloat and give me a speech on the futility of my mission?"

"No," she said. "I'm just going to kill you."

Then he threw her backward with a Force push. She hit a column hard enough to hear something crack, and staggered to her feet. Kenobi summoned his lightsaber back to his hand with a grin.

"Ventress, by all that is good in this galaxy, can we please settle this later?" He reached out in the Force, lifted her up, and plunked her a few meters farther down the corridor the way they had come. "Go!" he shouted.

--- Dark Disciple - Timeline : 19 BBY

Uses the Force to shove Maul aside a little enough to find a way to escape. It's impressive as Dooku feat, since Maul is also Kenobi's superior in the Force.

Obi-Wan heard her cry of surprise and felt her anguish rip through the Force. He shoved Maul away, moving to confront Savage, knocking him off balance as Adi fell to the ground, motionless. Maul sprang after Obi-Wan, aiming a killing blow at him from behind in hopes of catching his Jedi enemy in a moment of distraction. Obi-Wan sensed it coming and whirled with blinding speed, parrying Maul's attack. Then he jumped aside, knowing it would be a fatal mistake to be caught between the two Sith.

"Kenobi, this way!" someone yelled.

Obi-Wan realized it was Hondo.

He drew on the Force, shoving Maul and Savage aside. Adi's lightsaber leapt into his hand as he ran for the outpost, then retreated with Hondo and his men into the safety of their lair.

Overall, Kenobi is a very powerful Force user, certainly above of average Jedi Knights. He isn't powerful as Vader, Dooku or Maul, but he is powerful enough to compete with the likes of Ventress or Savage Opress.

I'd say Kenobi is more powerful than Savage Opress and Asajj Ventress, and reasonably inferior to Maul. Saying that he's on the level of Savage or Ventress is an understatement.

@yousufkhan1212: Savage is very powerful in the Force too, not sure how it's underestimation. Savage simply overpowered Jedi Master Grohto with a Force push, even Adi Gallia in a mid duel who can stomp Aurra Sing with the Force, he also knocks down Anakin and Obi-Wan with a Force repulse, and knock down a space shuttle with a Force blast, he even Force choked Dooku and Ventress when he is angry.

Ventress on the other hand, Force choked 4 people at the same time when she is angry, and also traded Force pushes with Obi-Wan and Anakin in their duel.

@erkan12: I'm pretty sure Obi-Wan can replicate those feats.

@erkan12: Why would obi wan force choke when it's against the Jedi Code to do so?

@nerevarine_11: What do you mean ?

@erkan12: I'm saying why would obi wan do the same things Savage or Ventress did when he's a Jedi not a dark side force user

@nerevarine_11: I didn't say he should. I said they were powerful enough to do those things.

@erkan12: Where did you find these TCW Magazines? Were they online?

@yousufkhan1212:

Maul is above of Kenobi in the Force.

@erkan12: I was asking where you found the Comic, not the name or cover.

@yousufkhan1212: You could use the search engines to find. Lol.

I was talking about the scans.

OK overall, but I feel some of these "feats" are not really that good.

1) The mercenaries, non Force sensitives, were caught off guard.

2) In Obsession, when he pushes away Anakin, Anakin is fighting Ventress, and is caught off guard.

3) Ventress was injured when Kenobi slammed her against the wall.

4) Anakin is Kenobi's clear superior in the Force. Anakin was hindered during that fight. Kenobi was also pushed back farther than Anakin.

5) Game mechanics are not canon in any way.

Not particularly powerful but he was proficient enough, Kenobi is like the guy who never got top marks in anything but was always good at everything.

Maul isn't Kenobi's superior, in any way.

Hella.

@kiadisandwich:

Yes, he is. By a rather solid margin, if we're talking Force.

Maul has casually Force choked Obi-Wan.

In Sith Hunters, a fully prepped Obi-Wan lunged at Maul, only to be insta choked. Kenobi was helpless, and would have died weren't it for another Jedi. The Choke was brief, but impactful. Kenobi was injured by it, and, as Plo Koon notes, unfit for battle as a result.

In Florrum, an amped Kenobi was Gripped by Maul. Although people have tried to debunk this by saying Kenobi was occupied with Savage, he WAS fully facing Maul when the attack was ready. Maul simply overpowered Kenobi.

Then, when Maul gets desperate amped, and amps cancel each other out (it was as if there were no amps) he blasts Kenobi across an entire cave, K.Oing him. Kenobi is fully prepped and ready to face Maul.

Maul landed three impactful TK hits on Kenobi during the TCW era.

Kenobi landed two, much less impactful, with circumstances.

The first one:

It was a severely out of practice Maul, who a day or two or even some hours prior struggled with simple tasks such as calling the lightsaber to his hand.

Maul had overcommitted and lost his balance, thus making it much easier for Kenobi to push him. Maul also had his back turned, and was unable to defend himself, unlike Kenobi, who was ready when Maul humiliated him.

The second one, he shoves Maul and Savage. The degree to success to which he did this, however, is unknown, and he was desperate to escape, given Gallia died. Desperation can be a useful boost.

As a Force wielder, Kenobi is roughly Ventress level, below Savage, and considerably below Maul.

Physically, Maul has dominated Kenobi. So, he's quite superior.

Saber-wise, they are roughly equals, but I see Maul taking a slight edge.

In the Force, yes he is.

If he was not, he would do this.
