Which is better for movies with Atmos?

The TCL Q75H. It has 5.1.2 channels, Dolby Atmos and DTS:X with up-firing speakers, while the JBL Bar 300W MK2 is a 2.1 bar limited to Dolby Digital and JBL Surround Sound.

Is the TCL worth about $190 more?

If you want Atmos height effects, an HDMI input and AirPlay 2, yes. If you mainly want loud bass and Bluetooth for less, the JBL at $229.95 covers that.

Which has better bass?

Both use a wireless 6.5-inch subwoofer. The TCL has more total power (up to 620W vs 300W), but the JBL's sub is tuned for deep bass in a 2.1 setup. Bass quality depends more on sub placement than on the wattage figure.

Which is easier to set up?

The JBL. It ships with an HDMI cable and wall-mount bracket, and connects over HDMI, optical or Bluetooth. The TCL needs eARC for best results and a Wi-Fi network for AirPlay 2.

Which fits a smaller room or TV stand?

The JBL. The TCL is 41.5 inches wide, so measure your stand or wall first. The JBL bar is more compact and includes a wall-mount kit.

Neither maker publishes a lifespan figure. The TCL has far more owner ratings (64 vs 1), which gives a better read on real-world reliability, but both are covered by standard manufacturer warranties.
