Vizio SB3621N-E8 2.1 Channel Soundbar (2017) vs Vizio SB3851-D0 5.1 Channel Soundbar (2016)

Analysis:

The Vizio SB3621N-E8 2.1 Channel Soundbar (2017) was loved by reviewers at CNET, a highly trusted source that performs reliable in-depth testing. It did great in its "The best speakers for 2020: Bose, Sonos, Yamaha, Vizio and more" roundup where it was named its "Best soundbar for the money", 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.

We couldn't find any sources that tested both of these Soundbars, so we only analyzed how they performed in reviews from different sites.

We first examined which sources rated each of these best and found that the Vizio SB3621N-E8 2.1 Channel Soundbar (2017) got its highest, 9, rating from Top Ten Reviews, while the Vizio SB3851-D0 Soundbar (2016) earned its best, 7.3, score from TechGearLab.

Lastly, we averaged out all of their review ratings and observed that the Vizio SB3621N-E8 2.1 Channel Soundbar (2017), with its 9.0 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 Vizio SB3621N-E8 2.1 Channel Soundbar (2017) 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.
