Short answer: the Sennheiser Ambeo Soundbar Plus. It ranks #5 of 27 all-in-one soundbars by sound quality, rated 3.9/5, at $839.99. The Bose Smart Ultra Soundbar ranks #12, rated 3.5/5, at $649, $190.99 cheaper, which does not close the gap in sound quality.
The Sennheiser Ambeo Soundbar Plus is the better-sounding choice. The Ambeo Plus places effects precisely around the room and sounds musical with stereo music too. The tradeoff: It cannot add rear speakers, so surround relies on processing.
Why pick the Bose Smart Ultra Soundbar: The Smart Ultra keeps voices front and center, and its AI Dialogue mode helps with mumbled lines. The tradeoff: Bass is thin for a bar this size until you add a Bose bass module.
Buy the Sennheiser Ambeo Soundbar Plus. It is rated higher for sound quality, and saving $190.99 with the Bose Smart Ultra Soundbar does not make up for the sound-quality gap.
