Rikkori
is mostly talking about the "subjective" stuff that rtings doesn't cover. Like what Vincent says in his review, eg: Worse motion (than X1E chipset models), worse upscaling, hardly any smooth gradation at all it seems (Which is worse than even original X1 chipset/85 series), and 50% less zones than XF/XG90.
As I said above I know people want a new model, and this is still the best value in 4K LCD 2020 imo, but its objectively worse in PQ than older Sony models that were similarly priced. It can support HDMI 2.1, has lower input lag and a snappier UI/better remote but if you don't about hold those three (3) things above the PQ then its a downgrade all round.
Its still a lovely TV and I would still recommend it over any other 4K LCD right now.
