Their top tier model in Pakistan is U9A, only available in 75" as 75U9A

I had the chance to review TCL C8 and P8 and compare it to my U7A and Q7 QLED, in short I was not impressed with either of them, U7A has higher nits than C8 and P8 and offers a better and brilliant picture. The Backlight matters a lot, higher the nits, the TV can present a picture with deeper blacks, hence the colours look great, the picture has that brilliance yet it shows all the detail in dark scenes. Now if the backlight is weak, not enough nits, then you have to increase brightness to get a details, but THAT greys out the dark scenes and make colours look a bit faded, ALSO, a huge difference is the backlight control, in C8 & P8 I observed some edge bleeding and uniformity issues, although they were minor but U7A looked better in this regard. In short that is the problem with C8 and P8, the panel is not bright enough. I would suggest that you audition them side by side with same input and check for yourself, most of the times these minor details don't bother people and other considerations like availability and pricing have to be factored in as well.
