Short answer: the TCL S55H. Both are rated 3.2/5 for sound quality (#14 and #15 of 16 soundbars with a subwoofer), and the TCL S55H costs $119.99 against $139.99 for the Ultimea Poseidon M60, so with nothing between them on sound quality, price settles it.
What the TCL S55H does well: The S55H adds a wireless subwoofer to the bar from the TCL S45H, so movies and music gain the low end that the bar alone lacks. It keeps a wired aux input, which the Ultimea Poseidon M60 lacks. Watch for: Surround and height effects are weak and the soundstage stays narrow, so it sounds like a front stereo pair with bass.
Why pick the Ultimea Poseidon M60: A compact bar with a dedicated center and a small wired sub that reaches surprisingly deep with tight, controlled bass. The tradeoff: Atmos and surround are virtual only, and the effect is barely noticeable.
Buy the TCL S55H. Both are rated the same for sound quality, and it costs $20 less than the Ultimea Poseidon M60.
