… but provided both are capable of holding a given amount of charge.. the capacitor can discharge much more quickly, often almost instantaneously.

With supercapacitors actually starting to be a thing, there isn’t the huge gulf of capability there used to be.

I've never measured any delay in a battery. I do agree that batteries have very different discharge characteristics than capacitors.

The capability gap is actually much larger even with super capacitors. Flow batteries make the possibility for huge increases in battery capacity.
