The video you linked is about two models only sold in the North American market, they aren't the same as in Europe. TCL in particular sell cut-down models in Europe.
The Hisense U8Q is similar to the H9F or H9G in that its a capable HDR TV, but the similarities end there. Its a entire different TV, made with different designers...from a different venture.
The thing with Chinese manufacturers in general like Hisense is they don't inflate there new TV prices quite the same as the Japanese and Korean manufacturers do, so its why Hisense models are priced so much cheaper now than other 2020 models. If you wait, the other models will also come down in price too...as will the Hisense ones, a little.
Options on 2019 TVs are thin on the ground. I keep advising people against purchasing 2020 models mainly because they are overpriced. The Hisense U8Q is priced better than others, but it will still get reduced in time. You also have to beware that if you buy a new 2020 model now its only been in the market for a couple of months so you can expect bugs galore. Not a good time to buy a TV at the moment.
The 3rd digit in the model name is irrelevant. The model that replaces the B9 is BX (B10 actually, but Roman numeral) and the C9 is replaced by the CX.
Its normal this time of year for 2019 models to sell out and 2020 models to replace them. Generally you'd be looking at about 10 months from now to see the BX for a similar price to the outgoing B9 but perhaps this Black Friday we will get lucky with a reduction. Never buy a TV each year before Black Friday, you will over pay. TVs are only released in summer each year, and the first time they become good value is Black Friday...sometimes even then they are too expensive, with spring each year (before the next new models are released) is the absolute best time to buy.
Often people come on here with a set budget, but they may not realise that depending on which time you choose to buy, you can get more for your money. This is a pattern repeated every year in the TV industry and it evolves around the new release of models which is usually between spring and...
