How is the Bose audio?

I’ve been looking at used 2025 EX90s, specifically Volvo buybacks, and have found some seemingly great deals. Less than 5k miles, full warranty, and faulty hardware replaced or repaired by Volvo, all for around $50k. These are Ultras, without the performance trim, so they have the Bose systems. I would prefer the B&W system, but those used EX90s seem to come in around $63k. Are the Bose systems still pretty great? Or is it worth it to keep an eye out for a better deal on the B&W?
