5 yrs ago I'd laugh my ass off and call you a dumbass if you mentioned Hisense, TCL, Vizio. At one time samsung was trash and it's traveling towards the trash direction these days. LG was a bootleg brand not too long ago.
The same way I research videogame systems I do TVs and what I found is this community is woefully misinformed about the evolution of technology. TCL makes their own parts so they can deliver quality at a lower price point than anyone else. I believe hisense has a patent on some new tech that makes them factors. There are specific reasons why each company is here and competing. Has basically nothing to do with just "this company makes good TVs"
No
Every company including Sony has its ups and downs when it comes to television. I just hate reading post that centers around what a person purchased because they become biased and ignorant about anything that is not what they just splurged on.
