I was going to say
Island level, but I don't want to bully BB haters too much right now so for now I am ok with saying
mountain level, look at this beauty:
SSG Mihawk's slash literally changed the shape of
the entire island , BB gets no damage from this attack because of his
high level CoA Haki is an incredible feat. BB already has one of the best CoA Haki feat in the series.
Another huge feat that how easily
BB overpowered Boa Hancock's CoC and CoA Haki with his own:
Before they were saying Hancock is YC1 level etc now watch what will they say:
What they were saying about BB's Haki and defense before:
People doubted how
Yami BB stomped Magellan later, called him YC3 level, his Haki is shit, hurt by Pre-TS Luffy jetpistol etc, yet Hancock's Hax is more dangerous than Magellan's Hax, when Blackbeard is serious
he easily overpowered Hancock's Hax and her Haki, same Hancock should be YC1.
Same Hancock with seastone cuffs were physically overpowering Magellan, and Yami BB can easily overpower her when she wasn't wearing any sea stone cuffs. That alone shows how Yami BB put Magellan in coma in the second fight when he got serious, and why Shiryu (Magellan's equal) accepted to become Yami BB's underling.
There is also the fact that Base BB (without any DF) went toe-to-toe with Captain Shanks (when Shanks dueled Mihawk),

I already explained here that Yami BB has mountain level defense
when he gets serious:
Of course BB haters were saying things like ''his Haki is shit'' etc, and lowballing him, but now they have no where to run.
Compare to the Admirals CoA Haki feat with BB's CoA Haki:
3 of them collectively as a team, stopping a random long range shockwave attack from Whitebeard, which is
1/3 of WB's Quake attack, its not as impressive as BB's CoA Haki feat, because the
shockwave didn't reshape the island, and its because blunt and shockwave attacks
are easier to stop it with CoA Haki in comparison with
piercing and cutting attacks:
''Armament Haki can protect me from blunt strikes... But my Haki isn't strong enough to handle this kind of damage yet...''
Its clear at this point,
Blackbeard's CoA > Admiral's CoA.
And not only that, you should also consider the fact that Rayleigh admits,
he couldn't defeat Blackbeard, even with Hancock's help.
Which is kind of confirmation that Blackbeard's CoA is above Admirals, and equal to Rayleigh's since,
Blackbeard was also dealing with Hancock in that moment.
If Rayleigh had much superior Haki than Blackbeard's, then the moment Rayleigh attacks Blackbeard, (who was holding Boa Hancock in that moment)
BB is in disadvantage, because he would have to take an attack from Rayleigh while holding Hancock.
Because he admits even
a surprise attack like he used on Kizaru (a kick that stopped Kizaru's attack and saved Zolo) from this position, wouldn't be enough to let Hancock go due to Blackbeard's Haki.
If Rayleigh could free Hancock in this position with a CoA attack, then surely that would be an advantage for Rayleigh, while Hancock distracts BB, Rayleigh could overpower BB's Haki easily if his Haki is superior, but IT IS NOT,
BB's CoA is superior to Admirals CoA Haki, and is on the same level with Rayleigh's CoA.
