Well, let's look at the tiers.
They would be above the Archangels of ToAru or at least in their physical versions, it is possible that there will be an update about them soon but at the moment they only have feats of moving the stars in the sky.
For speed they must defeat the double nerfed Magic Gods, in that mode they only say that they could destroy the universe only once and they would not have the power to recreate it and many characters were seen doing speed blitzes them.
They could be in the league of Coronzon in physical body, Crowley and Accelerator Platinum Wings.
Accelerator shook the galaxy to remove Coronzon's soul.

Although it is like the most emblematic feat, I think the best is the fact that with his field he stopped Coronzon's attack which is comparable to Othinus' spear that destroyed all the phases that she created (an exact number is not known because after the 10k phase they stopped counting but it has been pointed out that they were millions or hundreds of millions).

(Accelerator reflect that attack)
I'm not saying that he destroys universes with his blows, but I do say that he can work with that level of energy in his reflection.
There's also some discussion about how amazing it is that Accelerator summoned a metaphysical tree (Clonoth), which is a counterpart to the Sephiroth and Qliphoth that are apparently so large that they go through all the phases to hell and heaven respectively.
Although Accelerator's field works with passive calculations, he had a couple of good active calculation feats, although they occurred early in the series.
In other threads I tried to measure the calculation speed of Accelerator and a super computer from academy city, as the results are quite large I am going to copy and paste here to see more opinions on whether I made a mistake or if those calcs are working good.

Regarding speed, we have to say that Accelerator's attack shook the galaxy in seconds.
Othinus can control galaxies with her mind, Crowley reacted to Magic Gods stronger than her and Othinus's arrow traveled across the universe in seconds. It is the best of what is calculable.
What you mean "makes it clear it was annihilation"? The word "annihilation" isn't officially defined as subatomic destruction. That's just a fan made way to refer to it. And you underestimate dark matter. Being entirely different laws of physics with different photons and stuff it goes all the...

(Othinus' crossbow calc)
There are Big Bang bombs that attack in plank time but it is difficult to say if anyone scale from that attack. It also seems that between each phase that are basically universes and dimensions, there is quite a distance between each one, but it is not clear how much.
