We've seen the Juubi actually going all out and the best Bijuu Dama was fired in near ocean whose shockwave reached the alliance. That's it. Also the Tenpenchii feat which is just country level at best.
The previous panel (I know which panel you mean) are based on hearsay, that's what that character knew about the Juubi (Idk if Kakashi explained this one or not).
Plus, "world ending" statements are usually taken with a grain of salt. After all, WB's power was also said to destroy the world and his earthquakes reached several islands when he shifted the tectonic plates.
Again, that's a reason why I said Juubi's Bijuu Dama might come close to that.
No actually, we've never seen the Juubi going all out because there was no one in the alliance who could match even the V1 of it.
That shit slapped KCM2 Naruto and Eight tails together with one freaking hand, like an actual bitchslap.
The Juubi is stated to have no control of it's powers and therefore he wastes so much power whenever doing little things, it can't focus things.
Whatever power it outputs is much lesser compared to what it's actually capable of if it had a focused mind.
And then there's the fact that this is also the war arc Juubi which is massively incomplete and weaker compared to the ancient one.
The previous panel (I know which panel you mean) are based on hearsay, that's what that character knew about the Juubi (Idk if Kakashi explained this one or not).
The panel you talk about isn't hearsay, Kurama quite literally has the Juubis memories as he's a piece of it.
Plus Hagoromo raised Kurama and told/showed him even more than what his fragmented self knew, so the information can't be discarded as simply hearsay.
The Sage knows his stuff more than anyone bar Black Zetsu himself.
This sword was destroyed by pre PU Naruto and Sasuke including all key characters...
Plus, Hagoromo fought Kaguya. The Juubi is so much weaker than Kaguya.
The sword is based on will, come on I'm sure you remember this.
Obitos will was stated to be weak and wavering that's why those two could break it.
But the true power of that sword remains that it can remake the earth's surface.
Also how many days did Juubi need to destroy the planet's surface? Sure, he can keep spamming Bijuu Damas for all day but that's not how we gauge AP feats.
The battle wasn't stated to rage on for days or months like the anime stated.
In fact based on the timeline the battle was very much most likely for a whole day at most before they could seal it away.
Another point too, in Naruto the last Toneri admitted to the Juubis power being unrivalled and limitless.
Limitless might be hyperbole but the implication is pretty clear.
That's the most blatant admission of defeat ever.
In Boruto the Juubi is still stated to be more powerful than all powers combined which is mad crazy.
