Short answer: the Samsung HW-QS700F. It ranks #4 of 16 soundbars with a subwoofer by sound quality, rated 3.6/5, at $597.99; the LG S90TY ranks #8, rated 3.5/5, and costs $999.99, so there is not much of a tradeoff to weigh.
Why pick the Samsung HW-QS700F: Clear dialogue and a sub that delivers real weight make it a strong TV and movie upgrade, with a compact bar that sits flat or wall mounts. The tradeoff: Atmos effects lack precision and space compared with pricier rivals, and the sound can turn harsh at high volume.
Why pick the LG S90TY: A bar with a real wireless sub that suits both TV and music, with clear dialogue and a wide front stage. The catch: Without rear speakers the height effect only works for sounds in front, and RTINGS found Samsung Q800 bars such as the Samsung HW-Q800F wrap the room with Atmos far better.
Buy the Samsung HW-QS700F. It is rated higher for sound quality than the LG S90TY and costs less, which makes it the one to get unless you need something the other one does better.
