I was a die-hard Sony guy for years then I realized I've never had one that lasted more than 5 years. After reading numerous positive professional reviews I decided it was time to try the new "budget" brands. We moved to a new house 2 1/2 yrs ago and needed several new tvs. I treated myself to a LG C4 OLED for the bedroom and then three of the Hisense U8's in 55",65" and 100". This was Hisense's top of the line model at the time and they are mini-leds. The OLED was literally almost double the price of the U8's and to be sure, it's an excellent tv. But honestly, the U8's are the ones that frequently catch me thinking "wow, that looks fantastic". The 100" obviously loses a bit of image quality from the smaller ones but everyone that sees it is still pretty blown away by how good a screen that big can look. The LG has come down in price since then, in fact the C5 is less than I paid for the C4. The Hisense has actually gone up $100 for the 65" size. Not sure if that's reflective of a new confidence of the brand in the market or what. So the price difference is not as great as it was and if you've got to have an OLED then I get it. But if I had to buy another tv now I promise you it would be another Hisense U8, or possibly their new UR9, which costs more than any of the mid-grade OLEDS.
As an aside, Sony just handed over all of their TV production to TCL. They formed a new company that TCL owns 51% of. Sony will still develop their own processing, etc. I have never seen a TCL that impressed me much but I haven't looked in a few years. They may have some higher-end models that are quite impressive like Hisense does.
