Short answer: the Klipsch Flexus Core 100. It ranks #16 of 27 all-in-one soundbars by sound quality, rated 3.3/5, at $274.50. The Amazon Fire TV Soundbar Plus ranks #22, rated 3.0/5, at $189.99, $84.51 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the Klipsch Flexus Core 100 does well: This compact bar makes TV dialogue clear and adds real bass weight, which both TechRadar and Tom’s Guide credited in four-star reviews. Watch for: Atmos is processed rather than coming from height drivers, so overhead effects are faint.
Why pick the Amazon Fire TV Soundbar Plus: The Fire TV Soundbar Plus adds a center channel, which helps dialogue stand out, and it decodes Dolby Atmos and DTS:X from an eARC TV. The tradeoff: On its own the bass is thin, so films lack weight until the optional sub is added.
Buy the Klipsch Flexus Core 100. It is rated higher for sound quality, and saving $84.51 with the Amazon Fire TV Soundbar Plus does not make up for the sound-quality gap.
