How good is the optional B&O System in the 2025 Audi Q5?

I've never tried a B&O system before, only Burmester's from Mercedes in 2018 models, which had underwhelming bass.

I've seen the spec sheet and it is written to have 16 speakers with 685W of power in my region. (19 speakers in the US as far as I know)

Do you think the system sounds better than the optional Harman/Kardon system in the latest BMW X3?

I spend a long time in my car, so audio is an important part of the consideration. Thanks.
