Our Verdict

TCL Alto 8+

Roku Smart Soundbar

The Roku Smart Soundbar is a better overall soundbar than the TCL Alto 8+, though both bars perform very similarly. Neither bar supports Dolby Atmos content. However, they both give you access to a media streaming player - the Roku media player for the Roku bar and the Amazon Fire TV 4k media streamer for the TCL. The Roku supports Wi-Fi streaming and it has a companion app, unlike the TCL. The Roku also has a better-balanced sound when playing content through both its center channel and when downmixing surround content into stereo. However, the TCL has a more focused soundstage.
