Sonos Ultimate Immersive Set with Arc Ultra vs Samsung HW-Q990F

The Sonos Ultimate Immersive Set with Arc Ultra and Samsung HW-Q990F are both flagships catering to slightly different needs. The Sonos appeals to people who already have products from the Sonos ecosystem and who are familiar with using their phone as a remote. It has a slightly wider stereo soundstage and a punchier bass by default. Both soundbars have alright performance for height channels, though the Samsung may have an edge due to the greater audio format support. It also has more ports for HDMI In and Optical, which are absent on the eARC-only Sonos (unless you get an adapter for Optical). The Samsung's sound is more balanced out of the box as well, though both have sound enhancements that could tilt either in your favor.
