Verdict: Sonos Arc Ultra wins with 9.1.4 channels and DTS support versus Bose's 5.1.2 setup (per RTINGS and CNET). Bose provides clearer dialogue at a lower price but lacks Sonos multi-room flexibility. Choose Sonos for full Atmos immersion or Bose for straightforward TV enhancement.

Winner: Sonos Arc Ultra
