Our Verdict

LG SN9YG

Samsung HW-Q950A

The Samsung HW-Q950A is better than the LG SN9YG. The Samsung is an 11.1.4 setup with discrete satellites. It has better soundstage, center, surround, and Atmos performances. It even comes with a graphic EQ, unlike the LG. That said, the 5.1.2 LG is better-built.
