Our Verdict

Vizio SB2020n-G6

TCL Alto 5

The TCL Alto 5 is a better stereo 2.0 soundbar than the Vizio SB2020n-G6. It supports surround channels while the Vizio can't, which makes a big difference for movie watchers. It's also slightly better built. On the other hand, if you only want to watch some stereo content, the Vizio has a better-balanced bass, although its overall sound profile lacks a bit of detail in higher frequencies.
