LG B9 OLED vs Sony Z Series TVs (2018)
While the LG B9 OLED 55" wasn't able to make it to the very top of any roundups from sources that perform quality hands-on testing, it still got featured in a large number of them. What Hi-Fi?, HomeTheaterReview.com, TrustedReviews, Rtings, CNET, and AVForums have all deemed it worthy of a place on their respective shortlists.
Moving on to the Sony Z9 75" (2018): it was unable to reach the very top of any roundups from sources that conduct reliable and unbiased testing. Nonetheless, it still managed to impress reviewers from a number of such sites, like Rtings, PCmag, What Hi-Fi?, Techradar, and TrustedReviews, enough for them to include them on those lists.
When we thoroughly analyzed their review scores, we learned that all of the sources that tested both TVs, including What Hi-Fi?, TrustedReviews, and Rtings, preferred the LG B9 OLED 55" over the Sony Z9 75" (2018).
We also took a look at which sources they managed to impress the most. The LG B9 OLED 55" was liked best by What Hi-Fi?, which gave it a score of 10, while the Sony Z9 75" (2018) got its highest, 8.1, score from Rtings.
Lastly, we averaged out all of their review ratings and observed that the LG B9 OLED 55", with its 8.9 average, performed considerably better than most TVs - the mean score for the product category being 7.7 out of 10 - while the Sony Z9 75" (2018) managed an average of 7.7.
There's one caveat here - it might not be entirely justifiable to do a direct LG B9 OLED 55" vs. Sony Z9 75" (2018) review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
