Polk Audio Command Soundbar (2018) vs Vizio SB3851-D0 5.1 Channel Soundbar (2016)

Analysis:

The Polk Audio Command Soundbar (2018) (AM9640) was loved by reviewers at CNET, a highly trusted source that performs reliable in-depth testing. It did great in its "Best soundbars with Amazon Alexa in 2020" roundup where it was named its "Best value in an Alexa soundbar", which, in itself, makes it a product worth considering.

Taking a look at the Vizio SB3851-D0 Soundbar (2016), it got featured in roundups from two reliable sources that conduct their own testing - TechGearLab and Techradar - but it fell short of earning a top spot in either.

When we thoroughly analyzed their review scores, we learned that all of the sources that tested both Soundbars, including Techradar, preferred the Polk Audio Command Soundbar (2018) (AM9640) over the Vizio SB3851-D0 Soundbar (2016).

We also took a look at which sources they managed to impress the most. The Polk Audio Command Soundbar (2018) (AM9640) was liked best by soundandvision.com, which gave it a score of 10, while the Vizio SB3851-D0 Soundbar (2016) got its highest, 7.3, score from TechGearLab.

Lastly, we averaged out all of their review ratings and observed that the Polk Audio Command Soundbar (2018) (AM9640), with its 8.3 average, performed considerably better than most Soundbars - the mean score for the product category being 7.6 out of 10 - while the Vizio SB3851-D0 Soundbar (2016) managed an average of 7.2.

There's one caveat here - it might not be entirely justifiable to do a direct Polk Audio Command Soundbar (2018) (AM9640) vs. Vizio SB3851-D0 Soundbar (2016) review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
