Which is better for movies?

The Samsung. Its discrete rear and up-firing speakers place effects behind and above you, while the TCL creates height and surround through processing from a single bar.

Do I need a Samsung TV to use the HW-Q990H?

No. It works over HDMI eARC, optical or Bluetooth with any TV. Q-Symphony, which adds the TV's own speakers, only works with compatible Samsung TVs.

Which has better bass?

The Samsung, with two 8-inch drivers against the TCL's single 6.5-inch subwoofer. The TCL reaches down to about 45 Hz, which suits most living rooms.

Is the TCL enough for a small room?

Yes. A 5.1 bar with a wireless sub and calibration fills a small to medium room well. You lose true rear channels, so overhead and behind-you effects are less precise.

Which is easier to set up?

The TCL. It is one bar, one sub and one HDMI cable. The Samsung adds two rear speakers that need power outlets and placement behind the seating.

Is the Samsung worth stepping up to?

If you have the space and want real surround, yes. The extra channels, bigger subwoofer and Wi-Fi streaming are the main gains over the TCL.

Samsung HW-Q990H Soundbar vs TCL Q65H Q Class Soundbar

The Samsung HW-Q990H is the stronger system: a true 11.1.4 layout with dedicated rear speakers, dual 8-inch subwoofers and 756 W of amplification gives real object-based surround, and its 4.8/5 owner rating reflects that. The TCL Q65H is a simpler 5.1 bar with wireless sub, Dolby Atmos and DTS:X decoding, RAY·DANZ widening and AI room calibration, but it relies on processing rather than discrete rear channels. Buy the Samsung for a dedicated movie room; buy the TCL for a smaller room and a simpler setup.

Choose the Samsung HW-Q990H if you want genuine rear-channel surround, four height channels and the headroom for a large room.
Choose the TCL Q65H if you want Atmos and DTS:X in a simpler 5.1 package that fits a smaller space.
