Our Verdict

LG S90TR

Samsung HW-Q990D

The Samsung HW-Q990D is Samsung's flagship 11.1.4 soundbar. Although it has a similar configuration to the LG S90TR, the Samsung soundbar's well-rounded performance and feature set give it the edge over LG's mid-range offering. The Samsung bar sounds more balanced out of the box and performs better across all its channels. This is aided by the presence of upfiring drivers in its satellites and the bar itself, creating a more immersive Atmos sound that's great for movies. The Samsung bar also has more sound enhancement tools, including a graphic EQ. Plus, its HDMI 2.1 compatibility means it can be a great hub between your TV and console/PC. You can passthrough 4k signals at 120Hz 10-bit, resulting in a tear-free graphics performance that'll satisfy gamers. That said, if you already own an LG TV, the LG soundbar can connect to it wirelessly via WOW Cast, and you can even incorporate your TV speakers into the overall sound.
