It doesn't look like a personal opinion to me. I read so many reviews online and it is very easy to find on Google regarding Hisense and Vizio. Not just crap reviews but very meaningful ones. Just look at consumer affairs usa, I have also shared a video from stop the fomo in this thread itself where he personally says Hisense and Vizio are bottom of the pile in customer satisfaction and also has high rate of warranty claims, in India during initial period of A71F launch there were many TVs with DSE effect and warranty claim procedure wasn't smooth. There was a survey of 95,000+ Hisense TV owners and most of their TVs in USA didn't make it post warranty period. You can also check Amazon .com and their -ve reviews are no joke. I wouldn't recommend reading amazon.in reviews due to legitimacy issues.
I also saw a review on Vida OS where the user lost subtitles in Netflix. Now I can't share link for this because I saw this after deep milling through internet on Reddit forums.
Now let's talk common sense. Toshiba U8080 doesn't come with HDMI 2.1 so if we are using a 4k Firestick, you are locked at 4k @ 60FPS . If we want to enjoy the full potential of this TV then we are forced to use that buggy Vida OS. And with the latest update of Vida OS, they are forcing home page ads and with Vida OS they will push whatever they want you to see. Note: 900$ Hisense H9G in the US comes with Android OS.
And upscaling of these TVs are not comparable to Sony. I read this from many users not just from Amazon US reviews, you can find issues on Reddit, AVS forums as well. Upscaling of 720p - 1080p content on a Hisense is crap.
No just US, even Australia has the worst consumer satisfaction with Hisense TVs, check out whirlpool .au forums.
