This is such a hard question IMO. Now that I have an LG OLED set in my primary HT location, I notice every deficiency in my other set in my second HT location, a Samsung 4K set. The usages are a bit different, location 1 is primarily a dark room, and I also use it for gaming, while location 2 is a much brighter room, and no gaming.
I'd love to have another OLED there, maybe if I can a 55" OLED for a great price at some point... I've also been looking at the Samsung Q80R, as it checks most boxes, and its bright room performance is supposedly very good, but price wise it doesn't offer advantage if any over say a LG 55" C8.
