One other thing. You are viewing in a mostly dark room, therefore, look at OLED great found deals section because a 65" OLED from last year is well within your budget. Really, the only way you can decide is to get to a brick and mortar with a dark room and compare with your own eyes because this whole field is purely subjective. To many casual viewers, a perfectly calibrated reference screen will look dull and won't 'pop'. I personally prefer a bright screen and slightly unnaturally bright colors in a HDR movie and tend to still lean towards 3000 nit LCDs with lots of zones. If I was a sports fanatic or had only basic cable and was in a darker room, I would go with an OLED, they are superior to the best LCD on some fronts including blacks and motion.
I personally would go with the TCL over the Vizio P but I'd also either go with the smaller Vizio PQ 65" just for the vastly improved picture quality or wait a few months for a comparable quantum 75" to drop into your price range (which may well happen with a price war).
