I would probably turn any motion trickery off I always hated "intelligent" frame creation on my plasmas, I can see the unnatural motion straight away. I'm sure Vincent Teoh did a test that showed better motion on the panasonic even with everything turned off.JZ1000 (tba) or A80J will most likely be your best bet, and both should be under £2000 at BF. You can switch BFI on for SDR content without impacting brightness, and flicker should not be visible at the lowest setting. IIRC, Panasonic's implementation was the best for 2020. With no motion/BFI settings turned on, they should perform identically really; both use the same 120hz panels, so 24p content can be refreshed 5 times per frame without introducing any stutters.
So in theory the Pana and Sony you mention this year should be on par with LG for gaming too, but potentially better for film?
